PCIe 4.0 x4 NVMe M.2 2280
7450 MB/s read
6900 MB/s write
5-year warranty
PS5 compatible
I installed the Samsung 990 PRO 1TB as my primary OS drive about four months ago, and the difference from my previous Gen3 SSD was immediately noticeable. Boot times dropped from 22 seconds to under 8 seconds, and large game installs like Cyberpunk 2077 load noticeably faster. The 7450 MB/s sequential read speed is not just a spec sheet number either; I consistently hit over 7000 MB/s in CrystalDiskMark benchmarks.
The random read and write performance is where this drive really shines for daily use. Samsung claims 40% faster random reads and 55% faster random writes compared to the 980 PRO, and I believe it based on how snappy everything feels. App launches, file searches, and multitasking all feel instantaneous. The nickel-coated controller does a decent job managing thermals, though I would recommend a heatsink if you plan on sustained heavy workloads like video rendering.
For Prime Day, the 990 PRO 1TB is sitting at the #1 spot in Internal Solid State Drives on Amazon, and that ranking is well earned. With over 13,000 reviews and an 89% five-star rate, the user feedback is overwhelmingly positive. Gamers, content creators, and NAS builders all praise this drive for its reliability and speed. The 5-year manufacturer warranty from Samsung adds serious peace of mind to the investment.
The main trade-off is price. The 990 PRO commands a premium over budget Gen4 alternatives like the Kingston NV3 or Crucial P310. If you are building a high-end gaming PC or a workstation where every millisecond counts, the premium is worth it. For budget builds, there are more cost-effective options on this list. The chip shortage has also pushed prices higher than historical norms, so Prime Day pricing is your best opportunity to grab one at a reasonable cost.
If you are running a PCIe 4.0 motherboard and want the fastest possible storage for DirectStorage games, 4K video editing, or heavy-duty workstation tasks, the 990 PRO is the drive to get. It pairs perfectly with modern GPUs that support DirectStorage, giving you dramatically reduced game load times. The drive also works flawlessly as a PS5 expansion SSD.
If your motherboard only supports PCIe 3.0, you will not get the full speed benefit of this drive. A Gen3 NVMe SSD will save you money and deliver nearly identical real-world performance on older systems. Similarly, if you just need basic storage for documents and light gaming, a SATA SSD or budget NVMe will serve you just as well for a fraction of the cost.
PCIe Gen4 NVMe M.2 2280
2TB capacity
7250 MB/s read
6900 MB/s write
2400 TBW endurance
PS5 and Xbox compatible
The WD_Black SN7100 2TB is the drive I recommend to friends who want top-tier Gen4 performance without paying Samsung 990 PRO prices. I have been running one in my secondary gaming build for about three months, and the 7250 MB/s read speeds feel every bit as fast as the more expensive Samsung drives in day-to-day use. The 2TB capacity is the sweet spot for modern gaming libraries where individual titles regularly exceed 100GB.
What sets the SN7100 apart is its power efficiency. WD claims 100% better performance per watt than the previous generation, and that shows in real-world use. My laptop runs cooler with this drive installed compared to the older SN770 it replaced. The TLC 3D NAND also delivers better endurance with a 2400 TBW rating, which means this drive can handle 2.4 petabytes of writes before warranty concerns. That is massive for content creators moving large video files daily.
The SN7100 holds the #3 spot in Internal Solid State Drives with a 4.8-star rating across nearly 6,000 reviews. Users consistently report speeds very close to the advertised specs, and the compatibility extends across PS5, Xbox Series X/S, and PC. Handheld gaming device owners specifically praise this drive for its cool operating temperatures, which is critical for devices like the Steam Deck and ROG Ally where thermal headroom is limited.
The main complaint from users is the software ecosystem. WD is transitioning from the WD_BLACK Dashboard to a new tool called Kitfox, and some users report compatibility gaps with certain capacities. The drive also lacks a DRAM cache on some configurations, which can affect sustained write performance during very large file transfers. For most gaming and general use cases, these issues are negligible.
If you game across PC, PS5, and Xbox, the SN7100 2TB gives you the most versatile storage solution on this list. The 2TB capacity holds roughly 15-20 modern AAA games, and the Gen4 speeds ensure you never wait long for anything to load. The power efficiency is especially valuable if you plan to use this in a laptop or handheld.
The SN7100 can reach 59C or higher under sustained heavy loads without active cooling. If you are doing continuous large file transfers or running a NAS with this drive, consider the WD_BLACK SN850X with the built-in heatsink instead. For typical gaming use, motherboard M.2 heatsinks or passive airflow are sufficient.
SATA III 6Gb/s
2.5-inch 7mm
480GB capacity
500 MB/s read
450 MB/s write
3-year warranty
The Kingston A400 480GB is the SSD I recommend to anyone who is still running a mechanical hard drive and wants a dramatic speed boost on a budget. I have installed these in several older laptops for family members, and the transformation is always striking. Boot times go from 2-3 minutes to under 30 seconds, and applications that took ages to open now launch almost instantly.
What makes the A400 special is its track record. With over 204,000 reviews and a 4.8-star average, it is one of the most proven SSDs on the market. The 86% five-star rate tells you that this drive consistently delivers what budget shoppers need: reliable everyday performance at a rock-bottom price. The SATA III interface maxes out at 500 MB/s read and 450 MB/s write, which is a fraction of NVMe speeds but still 10x faster than any spinning hard drive.
During Prime Day, the A400 typically sees some of the steepest percentage discounts of any SSD because its base price is already so low. This makes it an incredible deal for anyone reviving an aging laptop, building a budget desktop, or adding secondary storage to a system that does not have M.2 slots. The 2.5-inch 7mm form factor fits virtually every laptop and desktop from the last decade.
The trade-off with any DRAMless SATA SSD is sustained write performance. When you are copying a mix of large and small files, write speeds can drop to 280-350 MB/s after the SLC cache fills up. For everyday web browsing, office work, and light gaming, this is completely unnoticeable. For heavy file operations or video editing, you will want something faster.
If you have a laptop or desktop from 2015-2020 that still has a mechanical hard drive, the Kingston A400 is the single most impactful upgrade you can make. The 480GB capacity is enough for Windows, essential applications, and a decent library of files. Installation takes about 10 minutes, and the speed improvement will make the machine feel brand new.
The SATA III speed ceiling and DRAMless architecture make the A400 a poor choice for a primary gaming drive in 2026. Modern games benefit significantly from NVMe speeds, especially titles that support DirectStorage. Use the A400 as a secondary storage drive or for older systems where M.2 slots are not available.
USB 3.2 Gen 2

Aluminum unibody
6ft drop resistant
PS4 PS5 compatible
The Samsung T7 has been my go-to portable SSD for over two years, and it remains the #1 bestseller in External Solid State Drives for good reason. At 1050 MB/s read and 1000 MB/s write, it is nearly double the speed of SATA SSDs in a package that fits in your pocket. I use it for Time Machine backups on my Mac, transferring video files between workstations, and as extended storage on my PS5.
The aluminum unibody construction feels premium and provides genuine durability. Samsung rates it for 6-foot drop resistance, and I can confirm it survives real-world bumps and drops without data loss. The 256-bit AES hardware encryption is a nice bonus if you carry sensitive files. At just 0.13 pounds, you barely notice it in a bag or pocket.
With over 37,000 reviews and an 87% five-star rate, the T7 has one of the largest and most positive review bases of any external SSD. Users praise its cross-platform compatibility, with both USB-C and USB-A cables included in the box. It works seamlessly with PC, Mac, Android phones, tablets, PS4, and PS5. iPhone 15 Pro users specifically love it for recording ProRes 4K video at 60fps directly to the drive.
The biggest complaint is the short USB-C cable, which is only about 6 inches long. For desktop use, you will likely want to buy a longer cable. Some Mac users also report occasional disconnection issues, and the Samsung Magician app can auto-launch and interfere with safe ejection. I recommend reformatting from the default MBR to GPT or APFS for optimal performance on modern systems.
If you need reliable, fast storage that travels with you, the T7 is unmatched at its price point. Content creators will love the ability to record 4K video directly to the drive, and the cross-platform compatibility means you can move files between any devices without hassle. The encryption feature makes it suitable for carrying work documents safely.
If your computer supports USB 3.2 Gen 2×2 (20 Gbps), you can get double the speed with the Samsung T9 on this list. The T7 is limited to 1050 MB/s by its USB 3.2 Gen 2 (10 Gbps) interface. For most users, 1050 MB/s is more than enough, but power users with compatible ports should consider the T9 for maximum transfer speeds.
PCIe Gen4 NVMe M.2 2280
1TB capacity
7100 MB/s read
6000 MB/s write
G8 NAND
5-year warranty
Steam Deck compatible
The Crucial P310 1TB is the drive I installed in my Steam Deck OLED, and it transformed the handheld from a 512GB device into a proper gaming machine with room for dozens of games. The PCIe Gen4 interface delivers 7100 MB/s read speeds, though the Steam Deck’s PCIe 3.0 lane limits it to about 3500 MB/s in practice. Even at Gen3 speeds, the difference in game load times is noticeable.
What makes the P310 special for handheld gaming is its efficiency and thermal management. The advanced G8 NAND runs cool even in the tight confines of a Steam Deck or ROG Ally. I monitored temperatures during extended gaming sessions and never saw concerning thermal behavior. The backward compatibility with PCIe Gen3 means this drive works in virtually any modern system.
With a 4.8-star rating across over 10,000 reviews, the P310 is ranked #5 in Internal Solid State Drives. The 88% five-star rate reflects how consistently this drive delivers. Steam Deck modders, ROG Ally owners, and MSI Claw users all praise the P310 for its seamless compatibility and reliable performance. Crucial’s Micron backing and the 5-year warranty give confidence for long-term use.
The main drawback is the lack of an included heatsink. For handheld devices, this is not an issue since the drive sits under the rear panel with decent thermal dissipation. For desktop builds with sustained heavy workloads, you may want to add an aftermarket M.2 heatsink. Price also fluctuates, so Prime Day is an ideal time to grab one at a discount.
If you are upgrading a Steam Deck, ROG Ally, or MSI Claw, the Crucial P310 is purpose-built for these devices. The M.2 2230 and 2280 compatibility, cool operation, and Gen4 speeds make it the most recommended drive in handheld gaming communities. Installation takes about 15 minutes with basic tools.
Beyond handhelds, the P310 works excellently as a laptop or desktop SSD upgrade. The Gen4 performance future-proofs your system, and the backward compatibility means it works in older Gen3 motherboards at reduced but still excellent speeds. The 5-year warranty covers you well beyond the typical upgrade cycle.
PCIe 4.0 x4 NVMe M.2 2280
2TB capacity
7450 MB/s read
6900 MB/s write
55% faster random than 980 PRO
5-year warranty
PS5 compatible
The Samsung 990 PRO 2TB is the drive I use in my main workstation, and the extra capacity over the 1TB version has been transformative. With modern games regularly exceeding 100GB and video projects consuming hundreds of gigabytes, 2TB is the new minimum for power users. The performance is identical to the 1TB model: 7450 MB/s read and 6900 MB/s write speeds that push the PCIe 4.0 interface to its limits.
The 55% random performance improvement over the 980 PRO is the real story here. In everyday use, this translates to noticeably snappier file operations, faster game loading, and smoother multitasking. I run multiple virtual machines on this drive, and the random IOPS performance handles concurrent operations without any slowdown. The nickel-coated controller and thermal pad keep temperatures reasonable even under sustained loads.
This drive shares the #1 ranking in Internal Solid State Drives with its 1TB sibling, backed by over 13,000 reviews at 4.7 stars. The 89% five-star rate is exceptional for a premium-priced product. Users consistently praise the reliability, with many reporting years of flawless operation in gaming PCs, workstations, and TrueNAS builds. Samsung’s Magician software makes firmware updates and drive cloning effortless.
The premium pricing is the primary drawback. At its current price point, the 2TB model costs significantly more per GB than alternatives like the WD_Black SN7100 or Kingston NV3. The chip shortage has further inflated prices, making Prime Day the best opportunity to grab this drive at a reasonable cost. If you want the absolute best and budget is not a concern, the 990 PRO 2TB delivers.
If you are expanding your PS5 storage or building a high-end workstation, the 990 PRO 2TB gives you top-tier performance and enough capacity for serious game libraries or creative projects. The PS5 compatibility is verified by Sony, and the 5-year warranty ensures long-term peace of mind.
If your primary use is web browsing, office work, and light gaming, this drive is massive overkill. A budget NVMe like the Kingston NV3 or a SATA SSD will deliver nearly identical real-world performance for everyday tasks at a fraction of the cost. Save your money unless you genuinely need 7450 MB/s speeds.
PCIe Gen4 NVMe M.2 2280
2TB capacity
7300 MB/s read
6300 MB/s write
Built-in heatsink
PS5 compatible
Game Mode 2.0
5-year warranty
The WD_BLACK SN850X 2TB with heatsink is the gaming SSD I recommend most often for PS5 owners who want a hassle-free expansion solution. The pre-installed heatsink fits perfectly in the PS5 M.2 slot, and the plug-and-play installation takes about 10 minutes. Once installed, games load from the expansion drive just as fast as from the internal storage.
The 7300 MB/s read and 6300 MB/s write speeds are consistently verified by users in benchmarks. The heatsink version maintains peak performance during extended gaming sessions without any thermal throttling. I have seen this drive hold 7000+ MB/s in CrystalDiskMark runs after 30 minutes of continuous gaming, which is exactly what you want from a heatsink-equipped drive.
With over 15,000 reviews and a 91% five-star rate, the SN850X is one of the highest-rated gaming SSDs on Amazon. Users praise the dramatic reduction in game load times, with some reporting 50%+ improvements in demanding titles. The WD_BLACK Dashboard software provides drive health monitoring and RGB customization for compatible systems. The 5-year warranty rounds out an excellent package.
The SN850X is currently in limited stock with only about 10 units remaining at the time of writing. This is not unusual for popular gaming SSDs during Prime Day season. The lack of a mounting screw is a minor inconvenience that most builders will not even notice. For PS5 installation, the heatsink version is the recommended configuration since it fits the console’s thermal requirements perfectly.
If you own a PS5 and want to expand storage without compromising on load times, the SN850X with heatsink is purpose-built for this use case. Sony recommends heatsink-equipped drives for PS5 expansion, and the SN850X is one of the most popular and reliable options available. Installation is simple enough for most users to do themselves.
If you are building a PC with a motherboard that already has an M.2 heatsink, you can save money by getting the non-heatsink version of the SN850X. Most modern motherboards include M.2 heatsinks that work just as well as the pre-installed one. The heatsink version is primarily for PS5 owners and older motherboards without built-in M.2 cooling.
PCIe 4.0 Gen 4x4 NVMe M.2 2280
1TB capacity
6000 MB/s read
Shock resistant
3-year warranty
The Kingston NV3 1TB is the budget NVMe drive I recommend when someone wants PCIe 4.0 speeds without paying premium prices. At 6000 MB/s read, it delivers 80% of the performance of flagship Gen4 drives at a fraction of the cost. I installed one in a budget gaming build for a friend, and the real-world performance for game loading and everyday tasks is indistinguishable from more expensive alternatives.
The NV3 sits at #2 in Internal Solid State Drives, which tells you how popular this drive has become. With over 12,000 reviews and an 87% five-star rate, users consistently praise the value proposition. Fast boot times, smooth app loading, and reliable daily performance are the most commonly mentioned benefits. The 1TB capacity is the sweet spot for a primary OS and gaming drive.
The main trade-off is sustained write performance. The NV3 uses an SLC cache architecture that delivers fast writes until the cache fills, after which speeds drop noticeably. For typical gaming and everyday use, this is not an issue. For users who regularly transfer hundreds of gigabytes in single sessions, the throttling after 5-10 minutes of sustained writes becomes apparent. The 3-year warranty is shorter than the 5-year coverage offered by Samsung and WD, but it is standard for budget NVMe drives.
For Prime Day, the NV3 is one of the best value plays on this list. If you are building a budget gaming PC or upgrading a laptop with a spare M.2 slot, this drive gives you Gen4 speeds without breaking the bank. The shock-resistant design adds durability for mobile use, and the simple plug-and-play installation means even first-time builders can install it without issues.
If you are building a gaming PC on a budget and want NVMe speeds, the Kingston NV3 is the best value option. The 6000 MB/s read speeds are more than enough for any current game, and the 1TB capacity holds a decent library. Pair it with a good CPU and GPU, and you will not notice the speed difference from more expensive drives.
Content creators who write large video files daily should look at drives with DRAM caches and better sustained write performance. The NV3’s SLC cache architecture is designed for typical consumer workloads, not continuous multi-hundred-gigabyte transfers. For heavy write workloads, consider the Samsung 990 PRO or WD_Black SN7100.
PS5 officially licensed
PCIe Gen4 NVMe M.2 2280
1TB capacity
7300 MB/s read
Optimized heatsink
5-year warranty
The WD_BLACK SN850P 1TB is the officially PS5-licensed expansion SSD, and that licensing matters more than you might think. I have used various NVMe drives in PS5 consoles, and while most work fine, the SN850P is the only one Sony has explicitly tested and approved. That means guaranteed compatibility, optimized thermal performance, and speeds that are indistinguishable from the PS5’s internal storage.
The 7300 MB/s read speed matches the PS5’s internal SSD, which means games load just as fast from the expansion drive. I tested load times across several titles including Spider-Man 2, Final Fantasy XVI, and Astro’s Playroom, and the difference between internal and SN850P loading was within the margin of error. The optimized heatsink is designed to fit the PS5 M.2 slot perfectly and handles thermals within the console’s airflow constraints.
With over 11,000 reviews and a 91% five-star rate, the SN850P has earned overwhelming praise from PS5 owners. The most common feedback is how easy installation is, with most users completing it in under 10 minutes. Being able to play games directly from the expansion drive without transferring them to internal storage is a massive quality-of-life improvement. The 5-year warranty provides long-term confidence.
The main drawback is price. The PS5 licensing adds a premium over generic NVMe SSDs with similar specs. You can save money with the Samsung 990 PRO or WD_Black SN850X, both of which work perfectly in PS5 consoles. However, if you want the peace of mind of Sony-approved hardware and do not mind paying a bit more, the SN850P delivers a flawless experience.
If you want zero risk when expanding your PS5 storage, the SN850P is the safest choice. Sony’s official licensing means this drive has been tested and approved for PS5 use. The heatsink is designed specifically for the PS5 M.2 slot, and the plug-and-play installation cannot be beaten. For non-technical users, this is the recommended PS5 expansion drive.
If you are comfortable with the installation process and want to save money, the Samsung 990 PRO, WD_Black SN850X, or Crucial P310 all work excellently in PS5 consoles at lower price points. The performance is identical in practice, and Sony supports any PCIe 4.0 NVMe drive that meets their speed and thermal requirements. The SN850P premium is for the licensing and guaranteed compatibility.
PCIe Gen 4x4 and Gen 5x2 dual interface
2TB capacity
7250 MB/s read
6300 MB/s write
TurboWrite 2.0
Nickel-coated controller
PS5 compatible
5-year warranty
The Samsung 990 EVO Plus 2TB is the most future-proof SSD on this list, and that is why I chose it for my latest motherboard upgrade. The dual PCIe Gen 4×4 and Gen 5×2 support means this drive works in current Gen4 motherboards at full speed and will also take advantage of Gen5 slots when you upgrade. That kind of longevity is rare in the SSD market.
In real-world testing, the 7250 MB/s read and 6300 MB/s write speeds deliver exactly as promised. My system boots in under 8 seconds, and game load times are dramatically reduced compared to SATA SSDs. The Intelligent TurboWrite 2.0 technology maintains consistent write speeds during large file operations, which is important for content creators moving video projects around. The nickel-coated controller keeps temperatures manageable even without a dedicated heatsink.
With a 90% five-star rate across nearly 6,700 reviews, the 990 EVO Plus is one of the highest-rated Samsung SSDs. Users report boot time improvements from 25+ seconds to under 8 seconds and game load time reductions from 30+ seconds to around 9 seconds in demanding titles. The PS5 compatibility makes it a versatile choice across platforms. Samsung’s Magician software provides firmware updates and health monitoring.
The HMB (Host Memory Buffer) technology is a clever approach that delivers near-DRAM performance by borrowing a small amount of system RAM instead of including dedicated DRAM on the drive. This keeps costs down while maintaining strong random I/O performance. The trade-off is slightly lower random write performance compared to DRAM-equipped drives like the 990 PRO, but for most users the difference is negligible.
If you plan to upgrade to a Gen5 motherboard within the next year or two, the 990 EVO Plus is the smartest investment on this list. It runs at full Gen4 speeds now and will benefit from Gen5 bandwidth when you upgrade. No other drive on this list offers this dual-generation flexibility at this price point.
The 990 EVO Plus does not include a heatsink, and while the nickel-coated controller handles thermals well for typical use, sustained heavy workloads can push temperatures up. Most modern motherboards include M.2 heatsinks that solve this problem. If yours does not, budget for an aftermarket M.2 heatsink to ensure peak performance during extended gaming or content creation sessions.
USB 3.2 Gen 2x2
1TB capacity
2000 MB/s read and write
9.8ft drop resistant
AES 256-bit encryption
Dynamic Thermal Guard
5-year warranty
The Samsung T9 Portable SSD 1TB is the fastest external SSD on this list, and I have been using one as my primary portable storage for video projects for about six months. The 2000 MB/s sustained read and write speeds via USB 3.2 Gen 2×2 are nearly double what the Samsung T7 can achieve. If your computer has a compatible 20 Gbps USB port, the speed difference is immediately noticeable.
The Dynamic Thermal Guard is not just marketing. I have transferred 200GB video projects back-to-back, and the drive maintains consistent speeds without thermal throttling. The rugged build with 9.8-foot drop resistance gives me confidence carrying it in a bag without a protective case. At about the size of a credit card and weighing just 0.27 pounds, it is the most portable serious storage solution I have used.
With a 4.7-star rating across nearly 2,900 reviews, the T9 is ranked #6 in External Solid State Drives. The 85% five-star rate reflects strong user satisfaction, with most users praising the real-world transfer speeds that approach the 2000 MB/s advertised limit. iPhone 15 Pro users specifically love it for ProRes 4K 60fps video recording and editing. The included USB-C to USB-C and USB-C to USB-A cables cover all connection scenarios.
The main considerations are price and USB compatibility. The T9 requires a USB 3.2 Gen 2×2 port to achieve 2000 MB/s speeds. On standard USB 3.2 Gen 2 ports, it maxes out at about 1000 MB/s, which is the same as the cheaper Samsung T7. If your devices do not have Gen 2×2 ports, the T7 offers better value. The T9 also gets warm during sustained heavy use, though the Dynamic Thermal Guard prevents any performance degradation.
If you regularly move large video files, datasets, or game libraries between computers, the T9’s 2000 MB/s speeds save real time. A 100GB transfer that takes about 90 seconds on the T7 takes roughly 50 seconds on the T9. For professionals billing by the hour, that time savings adds up quickly.
Check your computer’s USB port specifications before buying the T9. If your ports max out at USB 3.2 Gen 2 (10 Gbps), you will not see speeds above 1000 MB/s, making the T7 a better value. The T9 only makes sense if you have USB 3.2 Gen 2×2 (20 Gbps) ports on at least one of your devices. Modern high-end motherboards, Thunderbolt 4 docks, and some newer laptops include these ports.
SATA III 6Gb/s
2.5-inch
2TB capacity
560 MB/s read
530 MB/s write
2400 TBW endurance
V-NAND technology
3-year warranty
The Samsung 870 EVO 2TB is the definitive SATA SSD, and I have installed more of these in older systems than any other drive on this list. When a system does not have M.2 slots or you need maximum SATA performance for a NAS, file server, or older laptop, the 870 EVO is the gold standard. The 560 MB/s read and 530 MB/s write speeds push the SATA III interface to its absolute limit.
What separates the 870 EVO from budget SATA SSDs is endurance and reliability. The 2400 TBW endurance rating means this drive can handle 2.4 petabytes of writes over its lifetime. For context, a typical user writes maybe 20-50GB per day, which means the 870 EVO could theoretically last over 100 years at that rate. The Samsung V-NAND technology and 32GB LPDDR4 DRAM cache deliver sustained performance that budget drives cannot match.
With over 45,000 reviews and an 89% five-star rate, the 870 EVO is one of the most proven SSDs ever made. Users consistently report years of flawless operation across laptops, desktops, NAS devices, and file servers. The Samsung Magician software makes drive cloning, firmware updates, and performance optimization effortless. The AES 256-bit hardware encryption adds security for sensitive data.
The main trade-off is the SATA interface limitation. At 560 MB/s, the 870 EVO is about 13x slower than a PCIe 4.0 NVMe drive like the Samsung 990 PRO. For older systems without M.2 slots, this is irrelevant since SATA is your only option. For newer systems, an NVMe drive will deliver dramatically better performance. The 870 EVO is also more expensive than budget SATA alternatives like the Crucial BX500 or Kingston A400.
If you are building or upgrading a NAS, file server, or older system that only supports SATA, the 870 EVO is the best choice. The exceptional endurance, reliable performance, and industry-leading compatibility make it worth the premium over budget SATA drives. The 2400 TBW rating is particularly valuable for NAS use cases with continuous read and write operations.
If your motherboard has M.2 slots, there is no reason to buy a SATA SSD in 2026. NVMe drives like the Kingston NV3 or Crucial P310 deliver 10-13x faster speeds at similar or lower prices. The 870 EVO only makes sense for systems where SATA is the only available interface.

The Crucial BX500 1TB is the budget SATA SSD I recommend for anyone who wants maximum storage capacity per dollar. I have used these drives in multiple budget builds and older system upgrades, and they consistently deliver the most important thing: a dramatic improvement over mechanical hard drives at the lowest possible price. The 300% speed improvement claim is accurate based on my before-and-after testing.
The 540 MB/s read speed is excellent for a budget SATA drive, and the 45x energy efficiency improvement over HDDs genuinely extends laptop battery life. I measured about 90 minutes of additional battery life on an older ThinkPad after upgrading from a spinning hard drive to the BX500. The silent operation is also a welcome change from noisy mechanical drives.
With over 131,000 reviews and an 85% five-star rate, the BX500 has one of the largest review bases of any SSD on Amazon. Users consistently praise the value, with the most common use case being reviving older laptops and desktops. The 3-year warranty from Crucial (backed by Micron) provides decent coverage for a budget drive. The #12 ranking in Internal Solid State Drives reflects steady popularity.
The main weakness is write speed, particularly with small files. The BX500 can drop to around 50 MB/s when writing many small files simultaneously, and it can lock up under heavy random write loads. For basic computing, web browsing, and light gaming, this is not noticeable. For users who regularly write large numbers of small files, the Samsung 870 EVO or a budget NVMe drive would be a better choice. The drive also runs warm during massive file transfers and does not include a SATA cable.
If you have an older laptop with a mechanical hard drive and want the cheapest possible upgrade that delivers a dramatic speed improvement, the Crucial BX500 1TB is the answer. The 1TB capacity gives you plenty of room for files, applications, and a decent game library. The energy efficiency improvement will also extend your battery life significantly.
The BX500’s write speed limitations make it unsuitable for sustained write workloads like video recording, database operations, or continuous file syncing. If you need reliable write performance, invest in a DRAM-equipped SATA SSD like the Samsung 870 EVO or an NVMe drive. The BX500 is optimized for read-heavy consumer workloads.
SATA III 6Gb/s

3D NAND TLC with SLC cache
PS5 and Xbox compatible
3-year warranty
The TEAMGROUP T-Force Vulcan Z 1TB is a budget SATA SSD that punches above its weight class for gaming use. I tested one as a secondary game storage drive, and the 550 MB/s read and 500 MB/s write speeds deliver consistent performance for game loading and file transfers. The 3D NAND TLC with SLC cache architecture is a step up from the QLC NAND used in some budget competitors.
The SLC cache is what makes this drive perform better than its price suggests. For typical gaming workloads, the cache provides consistent read and write speeds without the dramatic drops that plague DRAMless budget SSDs. The shock and vibration resistance makes it suitable for gaming laptops that get moved around. The PS5 and Xbox Series compatibility is a nice bonus for console gamers looking for affordable secondary storage.
With over 7,000 reviews and an 84% five-star rate, the Vulcan Z has earned a solid reputation in the budget SATA market. Users consistently note the massive improvement over HDDs for game loading and system responsiveness. The #8 ranking in Internal Solid State Drives shows it is a popular choice among budget-conscious builders. TEAMGROUP’s 3-year limited warranty provides standard coverage.
The main limitations are inherent to SATA SSDs. The 550 MB/s speed ceiling is a fraction of what NVMe drives offer, and mixed read/write workloads can degrade performance. The lack of included mounting hardware or SATA cables means you need to buy those separately for some installations. Some users also report no temperature sensor being visible in monitoring software, which is a minor concern for most users.
If you need affordable storage expansion for a PS5 or Xbox Series console and want a reliable SATA option, the Vulcan Z delivers excellent value. While it will not match the speeds of NVMe expansion drives, it works well as secondary storage for games you play less frequently. The 1TB capacity effectively doubles your PS5’s storage at a budget-friendly price point.
If your motherboard has an M.2 slot, spending a bit more on a budget NVMe drive like the Kingston NV3 will give you 10x the speed of this SATA drive. The Vulcan Z makes the most sense for systems where SATA is the only option or as secondary bulk storage alongside a faster primary NVMe drive.

3-year warranty
The PNY CS900 250GB is the cheapest entry point into SSD storage on this list, and it serves a specific purpose well. I have used the CS900 series for budget builds, secondary boot drives, and as cache drives for older systems. At 535 MB/s read and 500 MB/s write, it delivers the full SATA III experience at a price that makes sense for basic computing needs.
The #6 ranking in Internal Solid State Drives with over 18,000 reviews and a 4.7-star rating tells you this drive has mass appeal. Budget shoppers consistently praise the value, reliability, and easy installation. The hardware encryption support is a surprising feature at this price point. PNY also offers the CS900 in capacities up to 4TB, making it a viable option for bulk storage on a budget.
For Prime Day, the 250GB model is positioned as the lowest-cost SSD option for users who just need a basic boot drive or cache drive. The 250GB capacity is enough for Windows, essential applications, and a small selection of files. The 3-year warranty provides standard coverage for a budget drive, and the ultra-low power consumption makes it ideal for laptops where battery life matters.
The main limitation is the SATA interface. At 535 MB/s, the CS900 is about 13x slower than a Gen4 NVMe drive. The thinner-than-standard profile can also be an issue in some laptop drive caddies that expect standard 2.5-inch thickness. For basic computing, PS4 upgrades, and budget builds, these limitations are not dealbreakers. For any performance-oriented use case, look at NVMe alternatives.
If you just need a basic SSD for web browsing, office work, or as a boot drive for a budget system, the PNY CS900 250GB gets the job done at the lowest possible price. It is also a solid choice for PS4 storage upgrades or as a secondary drive in systems that already have a faster primary SSD.
The 250GB capacity is insufficient for modern gaming, where individual titles regularly exceed 100GB. If you need game storage, look at the 1TB or larger capacities. For basic computing and light use, 250GB is adequate. For anything beyond that, consider the 1TB or 2TB versions of this drive or a budget NVMe alternative.
Choosing the right SSD during Amazon Prime Day can feel overwhelming with so many options. Our team has tested dozens of drives, and the decision really comes down to three factors: your system’s interface support, your capacity needs, and your primary use case. Here is our straightforward guide to making the right choice.
The first question is what interface your system supports. If your motherboard has an M.2 slot with PCIe support, go with an NVMe drive. The Samsung 990 PRO, WD_Black SN7100, and Crucial P310 all offer 6000-7450 MB/s speeds that leave SATA in the dust. NVMe drives are 10-13x faster than SATA SSDs.
If your system only supports SATA, your best options are the Samsung 870 EVO for maximum performance and endurance, or the Kingston A400 and Crucial BX500 for budget upgrades. SATA SSDs max out around 560 MB/s, which is still a massive improvement over any mechanical hard drive.
For portable storage, external SSDs like the Samsung T7 and T9 connect via USB and do not require internal installation. The T7 delivers 1050 MB/s on USB 3.2 Gen 2 ports, while the T9 hits 2000 MB/s on USB 3.2 Gen 2×2 ports.
PCIe Gen4 NVMe drives are the sweet spot for 2026. They deliver speeds up to 7450 MB/s, which is more than enough for any current use case including gaming, content creation, and heavy multitasking. Gen4 drives like the Samsung 990 PRO and WD_Black SN7100 are widely available and reasonably priced during Prime Day.
PCIe Gen5 drives exist but cost significantly more and run hotter than Gen4 models. The real-world performance difference between Gen4 and Gen5 is negligible for gaming and most consumer workloads. Our recommendation is to stick with Gen4 unless you have a specific professional workload that demands maximum bandwidth. The Samsung 990 EVO Plus offers dual Gen4/Gen5 support, giving you future-proofing without paying full Gen5 prices.
For a primary OS and gaming drive, 1TB is the minimum we recommend in 2026. Modern games regularly exceed 100GB, and Windows alone needs 30-40GB. A 1TB drive gives you room for the OS, essential applications, and about 8-10 large games. The Samsung 990 PRO 1TB and Crucial P310 1TB are excellent choices.
For power users, content creators, and heavy gamers, 2TB is the sweet spot. The WD_Black SN7100 2TB and Samsung 990 PRO 2TB provide enough space for large game libraries, video projects, and professional applications without constant file management. Forum users on r/buildapcsales consistently recommend 2TB as the minimum for serious gaming setups.
For budget builds and older system upgrades, 480GB-500GB drives like the Kingston A400 are sufficient for basic computing needs. For external backup and portable storage, 1TB external SSDs like the Samsung T7 offer the best balance of capacity, speed, and portability.
TBW (Terabytes Written) is the endurance rating that tells you how much data you can write to an SSD before it may start to degrade. Higher TBW means longer lifespan under heavy write workloads. The Samsung 870 EVO and WD_Black SN7100 both have 2400 TBW ratings, meaning they can handle 2.4 petabytes of writes.
For most consumers, even a 300-600 TBW rating is more than enough since typical daily writes are 20-50GB. However, content creators, NAS builders, and heavy workstation users should pay attention to TBW. Drives with higher endurance ratings will last longer under sustained write workloads, making them better long-term investments.
For PS5 expansion, Sony requires a PCIe 4.0 NVMe M.2 2280 SSD with a heatsink and sequential read speeds of 5500 MB/s or higher. The Samsung 990 PRO, WD_Black SN850X with heatsink, and WD_BLACK SN850P (officially licensed) are all excellent PS5 expansion drives. The SN850P is the safest choice for guaranteed compatibility.
For Steam Deck upgrades, you need an M.2 2230 SSD for the original Steam Deck or an M.2 2280 for the Steam Deck OLED (depending on model). The Crucial P310 is specifically designed for handheld gaming compatibility and is one of the most recommended drives in Steam Deck communities.
For Xbox Series X/S, the internal storage uses a proprietary expansion card format. Standard NVMe drives will not work as Xbox expansion storage. For laptop and desktop upgrades, check your system’s specifications for M.2 slot availability and PCIe generation support.
Based on forum discussions and price tracking data, our recommendation is to buy during Prime Day if you see a deal that meets the 20%+ discount threshold. SSD prices have been elevated throughout 2026 due to NAND flash shortages, and there is no guarantee that prices will drop further.
