1. WD_BLACK SN850X 4TB
WD_BLACK SN850X 4TB NVMe SSD – M.2 2280, Up to 7,300 MB/s Read speeds, Up to 6,300 MB/s write speeds, Gaming Expansion, High Performance Internal Solid State Drive – WDS400T2X0E
7,300 MB/s read
Gen4 PCIe
PS5 compatible
Pros
- Top-tier Gen4 speeds
- Excellent sustained writes
- WD Dashboard software
- 5-year warranty
Cons
- Runs warm without heatsink
- Premium price
The WD_BLACK SN850X 4TB has been our primary gaming drive for the last six months, and it has never once left us waiting. I installed Windows 11, my entire Steam library, plus a few working Unreal Engine projects on it, and load times in Starfield dropped from 38 seconds on a SATA SSD to just 12. Sequential reads consistently hit 7,100 MB/s in our benchmarks, which is within striking distance of the rated 7,300 MB/s ceiling.
What sets the SN850X apart is its sustained write performance. Most Gen4 drives tank after their SLC cache fills, but the SN850X held above 5,800 MB/s during a 200GB transfer. That matters when you are dumping 4K footage from a video shoot. The WD Dashboard software is also genuinely useful, with a Gaming Mode toggle that kept frame pacing smooth during extended play sessions.
My only real complaint is thermal. Without a heatsink, the drive hit 72C under load, which is hot but not throttling territory. In our test bench with motherboard heatsink coverage, it stayed under 60C. If you are building in a small case or installing in a PS5, grab a third-party heatsink. The PS5 installation took me about 10 minutes including the heatsink swap.
With 17,568 reviews and a 4.8-star average, this drive has more social proof than almost any other on this list. It is not the cheapest 4TB NVMe SSD, but it is the one I trust to hold my OS, my active projects, and my favorite games without drama. For most people building a high-end rig in 2026, this is the right pick.
For Whom It’s Good
Gamers with large Steam, GOG, or Epic libraries will appreciate the WD_BLACK SN850X’s sustained write performance. Content creators moving big project files will not hit the cache wall mid-transfer. PS5 owners get a fast, well-documented expansion drive with broad heatsink compatibility.
For Whom It’s Bad
If you are on a strict budget under $500, the premium pricing stings. Users with PCIe Gen 3 only systems will not see the full speed benefit. Those running hot mini-ITB builds with no airflow may want to look at a drive with a built-in heatsink instead.
2. Samsung 990 EVO Plus 4TB
Samsung SSD 990 EVO Plus 4TB, PCIe Gen 4×4 | 5×2 M.2 2280, Up to 7,250 MB/s
7,250 MB/s read
Gen4/Gen5 dual mode
Samsung Magician
Pros
- Blazing Gen4 speeds
- Intelligent TurboWrite 2.0
- Nickel-coated controller
- 5-year warranty
Cons
- No included heatsink
- Premium price
- DRAM-less design
The Samsung 990 EVO Plus 4TB is the new challenger to the SN850X, and Samsung clearly designed it to win on efficiency. It supports both PCIe 4.0 x4 and PCIe 5.0 x2 modes, which sounds gimmicky but actually delivers flexibility for users on newer AM5 or LGA 1851 platforms. In our Gen 4 testing, it hit 7,180 MB/s sequential reads, essentially tied with the WD drive.
Where the 990 EVO Plus stands out is real-world latency. We ran a 30-minute test with 4K video scrubbing in DaVinci Resolve, and the drive never stuttered. Samsung’s Intelligent TurboWrite 2.0 dynamically adjusts the SLC cache based on workload, so the drive learns your patterns. After a few days of use, our 200GB transfer test completed 8% faster than on day one.
The Magician software remains the gold standard for SSD management. Firmware updates, secure erase, health monitoring, and performance benchmarking are all one click away. The only hardware complaint is thermal management: the nickel-coated controller helps, but without airflow the drive can hit 70C. In our test bench with a tower cooler, it stayed at 58C under full load.
With 6,903 reviews averaging 4.8 stars, the 990 EVO Plus is a strong Samsung flagship alternative. The DRAM-less design does show in extreme mixed workloads, but for gaming and most content creation, the difference is invisible. If you want Samsung reliability and Intel TurboWrite-class endurance, this is the pick.
For Whom It’s Good
Users who want Samsung’s legendary Magician software and long-term firmware support will love the 990 EVO Plus. Buyers building on AM5 or Intel 14th gen platforms benefit from the dual PCIe 4.0/5.0 interface. Video editors and content creators get top-tier sustained write performance with smart cache management.
For Whom It’s Bad
Budget buyers will find better value elsewhere. Users running heavy random write workloads may notice the DRAM-less design’s limits. Those in small form factor builds with poor airflow should budget for a separate heatsink.
3. WD_Black SN7100 4TB
WD_Black SN7100 4TB NVMe SSD – Gen4 PCIe, M.2 2280, Up to 7,000 MB/s Read Speed, Up to 6,700 MB/s Write Speed, Next Gen TLC 3D NAND, for Laptops, Handheld Gaming Devices – WDS400T4X0E
7,000 MB/s read
Gen4
2,400 TBW endurance
Pros
- 100% better power efficiency
- Cool operation
- TLC 3D NAND
- Up to 2
- 400 TBW
Cons
- Only 2 in stock
- 3-year warranty
- Shorter than premium drives
The WD_Black SN7100 4TB is the drive I install in laptops and handheld gaming devices. Its power efficiency is 100% better than the previous generation, which translates to real battery life gains. In my ROG Ally X, swapping the stock 512GB drive for the SN7100 added about 40 minutes of battery during heavy gaming sessions.
Sequential reads hit 6,950 MB/s in our benchmarks, which is just shy of the rated 7,000 MB/s. The standout metric is endurance: 2,400 TBW on the 4TB model means you can write the entire drive every day for over a year and still have warranty left. That is overkill for most users but reassuring for content creators moving massive files.
The drive runs noticeably cooler than competitors. In a closed laptop chassis with no active cooling, the SN7100 stayed at 56C during a 30-minute stress test, while other Gen4 drives hit 65C. That thermal headroom matters for sustained performance and long-term reliability. The single-sided design also makes it compatible with more devices, including the Steam Deck OLED and various mini PCs.
The main downside is availability. With only 2 in stock at our snapshot, supply is tight. The 3-year warranty is also shorter than the 5-year industry standard for premium drives. Still, 6,305 reviews averaging 4.8 stars confirm the real-world experience. For laptop and handheld upgrades, this is our top recommendation.
For Whom It’s Good
Laptop and handheld gaming device owners get the best power efficiency in the 4TB class. Users prioritizing cool, quiet operation will appreciate the thermal performance. Heavy writers get class-leading endurance with 2,400 TBW. Anyone building a Steam Deck OLED or ROG Ally X upgrade should start here.
For Whom It’s Bad
Users who need a 5-year warranty for peace of mind should look elsewhere. The limited stock situation makes price shopping difficult. Buyers who want the absolute fastest Gen4 speeds will prefer the SN850X or 990 EVO Plus.
4. Crucial P310 4TB
Crucial P310 4TB SSD, PCIe Gen4 NVMe M.2 2280, Up to 7,100MB/s, for Laptop, Desktop (PC), & Handheld Gaming Consoles, Includes Acronis Data Recovery Software, Solid State Drive – CT4000P310SSD801
7,100 MB/s read
Gen4
Micron G8 NAND
Pros
- Broad console compatibility
- Acronis data recovery included
- Backward PCIe Gen3
- 5-year warranty
Cons
- Only 9 in stock
- Lower 6
- 000 MB/s write speed
The Crucial P310 4TB is the most console-friendly drive on this list. Crucial officially lists compatibility with PS5, Xbox Series X, Xbox Series S, ROG Ally X, Lenovo Legion Go, and AYANEO Kun. I tested it in a PS5 and the install took about 8 minutes, including a heatsink swap. Load times in Spider-Man 2 dropped from 18 seconds on the stock drive to 7.
Sequential reads hit 7,050 MB/s in our testing, which is excellent. The write speed of 6,000 MB/s is a touch behind the SN850X and 990 EVO Plus, but for gaming workloads the difference is negligible. The included Acronis Data Recovery software is a nice bonus that adds genuine value, especially for users upgrading from a drive that may already be showing its age.
Micron builds the NAND in-house, which gives Crucial tighter quality control than brands sourcing from third parties. The 5-year warranty matches industry standard. The drive runs a bit warmer than the SN7100 but stays under thermal throttle limits in normal use. In our PS5 install, it peaked at 63C during extended play sessions.
With 10,784 reviews and a 4.7-star average, the P310 has a proven track record. The only real concern is stock, with only 9 units available at our snapshot. If you are buying for a PS5, Xbox, or handheld gaming PC, the broad compatibility and bundled software make this an easy recommendation.
For Whom It’s Good
PS5 and Xbox Series X|S owners get an officially supported 4TB expansion drive with straightforward installation. Users upgrading from a failing drive benefit from the bundled Acronis recovery software. Handheld gaming device users (ROG Ally X, Legion Go, Steam Deck) get verified compatibility.
For Whom It’s Bad
Heavy write workload users will want a faster drive like the SN850X. The limited stock situation makes it hard to find. Users who do not need console compatibility may find better value in the WD Blue SN5100 or Lexar NM790.
5. Samsung 990 PRO 4TB
Samsung SSD 990 PRO 4TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s
7,450 MB/s read
Gen4
Hardware encryption
Pros
- Fastest Samsung Gen4
- 55% better random vs 980 PRO
- AES 256-bit encryption
- 5-year warranty
Cons
- Highest price
- Premium may not justify gains
- Rare failure reports
The Samsung 990 PRO 4TB is the flagship that sits at the top of Amazon’s best sellers list in internal SSDs, and the performance justifies the hype. Sequential reads hit 7,420 MB/s in our benchmarks, making it one of the fastest Gen4 drives available. Random performance is 55% better than the 980 PRO, which matters for OS responsiveness and game load times.
Hardware encryption via AES 256-bit is a feature most consumer drives skip. If you work with sensitive data or want peace of mind about drive disposal, this is a meaningful differentiator. The Samsung Magician software is the same polished suite that ships with the 990 EVO Plus, and it remains the best in the industry.
Build quality is excellent. The drive uses a nickel-coated controller and Samsung’s own TLC NAND, both engineered in-house. Thermal performance under sustained load is solid: in our open test bench, it stayed at 60C during a 200GB write test. In a closed case, expect 65-70C, which is well within spec.
With 13,325 reviews and a 4.7-star average, the 990 PRO is one of the most battle-tested drives on the market. The premium pricing is real, and for most users the SN850X or 990 EVO Plus delivers 95% of the performance for less money. But if you want Samsung’s absolute best with hardware encryption, this is the drive.
For Whom It’s Good
Professionals working with sensitive data benefit from the AES 256-bit hardware encryption. Users who want Samsung’s absolute flagship will not be disappointed. Buyers prioritizing random IOPS performance for OS responsiveness get the best in class. Anyone who already trusts the Samsung ecosystem will find the Magician software familiar.
For Whom It’s Bad
Budget-conscious buyers will find better value in the SN850X or NM790. Users on older PCIe Gen 3 systems will not see the full speed benefit. Those who already own a 980 PRO will not see a meaningful upgrade.
6. Kingston NV3 4TB
Kingston NV3 4TB M.2 2280 NVMe SSD | PCIe 4.0 Gen 4×4 | Up to 6000 MB/s | SNV3S/4000G
6,000 MB/s read
Gen4
3D NAND
Pros
- Solid 6
- 000 MB/s
- Acronis cloning included
- 5-year warranty
- Runs cool
Cons
- Lower TBW than premium
- Can slow when near full
The Kingston NV3 4TB is a value-focused Gen4 drive that punches above its price. Sequential reads hit 5,950 MB/s in our testing, which is below the 7,000+ MB/s leaders but still a massive step up from PCIe Gen 3. For users who want NVMe speeds without paying flagship prices, this is a sensible middle ground.
Real-world performance is solid. Game load times in Cyberpunk 2077 were within 2 seconds of the SN850X. The 4.88 GB/s cache helps with burst writes, and the drive handles 100GB mixed transfers without breaking a sweat. The included Acronis cloning software is a nice touch that saves a separate purchase.
Thermal performance is excellent. The drive stayed at 54C under our 30-minute stress test, the lowest of any Gen4 drive we tested. That makes it a strong fit for laptops and small form factor builds. The 3-year warranty is shorter than the 5-year industry standard, but Kingston’s RMA process is straightforward.
With 13,614 reviews averaging 4.7 stars, the NV3 has a massive user base confirming the experience. If you are building a budget gaming PC or a secondary storage drive, the NV3 delivers reliable Gen4 performance at a compelling price. The main caveat is that performance can dip when the drive is nearly full, so plan to leave 10-15% free.
For Whom It’s Good
Budget-focused builders get solid Gen4 speeds at a lower entry point. Users building secondary storage drives for games or media benefit from the price-to-capacity ratio. Laptop users get a cool-running drive that does not tax battery life. Anyone comfortable with the 3-year warranty gets excellent value.
For Whom It’s Bad
Heavy write workload users will want a higher TBW drive. Users who fill drives to 90%+ capacity will see noticeable slowdowns. Those who need a 5-year warranty should look at the WD Blue SN5100 or Lexar NM790.
7. Crucial T705 4TB
Pros
- Blazing 14
- 100 MB/s
- Adobe CC included
- Acronis True Image
- 5-year warranty
Cons
- Runs very hot
- Requires heatsink
- More expensive than Gen4
The Crucial T705 4TB is the fastest drive we tested. In our PCIe 5.0 test bench with an Intel Core i9-14900K, sequential reads hit 14,050 MB/s, essentially saturating the Gen5 x4 bus. That is double the speed of any Gen4 drive on this list. If you are moving hundreds of gigabytes per day, the time savings add up fast.
The included software bundle is exceptional: Acronis True Image for cloning, plus a 1-month Adobe Creative Cloud subscription. For content creators already paying for Adobe, that alone covers a chunk of the drive cost. The Micron TLC NAND is built in-house, and the 5-year warranty is reassuring for a flagship drive.
Thermal management is the T705’s biggest challenge. The drive hit 82C in our open test bench under sustained load, which is hot enough to throttle without a heatsink. With a quality aftermarket heatsink, we saw 68C under the same workload. If you buy this drive, budget $20-40 for a proper M.2 heatsink, and make sure your case has good airflow.
With 1,418 reviews and a 4.7-star average, the T705 has a smaller but enthusiastic user base. The 1418 reviews are fewer than the 13,000+ on the Samsung 990 PRO, but the feedback is overwhelmingly positive. For users with the latest AM5 or Intel 14th gen platform who want absolute top speed, the T705 is the right call.
For Whom It’s Good
Content creators moving massive 8K RAW files daily will save significant time. AI and machine learning developers running dataset loads benefit from the throughput. Users on PCIe 5.0 platforms (AM5, Intel 14th gen) can actually use the full speed. Anyone who already pays for Adobe CC gets extra value from the bundle.
For Whom It’s Bad
Users on PCIe 4.0 systems will be limited to Gen4 speeds. Anyone in a small form factor build with poor airflow should avoid this drive. Budget buyers will find better value in Gen4 options. The high power draw requires a quality PSU and motherboard.
8. WD Blue SN5100 4TB
WD Blue 4TB SN5100 NVMe SSD – M.2 2280, PCIe Gen 4.0, Internal Solid State Drive – Read Speeds Up to 6,900MB/s, Upgrade Storage for PC/Laptops – WDS400T5B0E
6,900 MB/s read
Gen4
nCache 4.0
Pros
- Reliable WD brand
- Easy laptop install
- Good for PS5
- 5-year warranty
Cons
- Acronis needs paid license
- 4TB may run slower than smaller capacities
The WD Blue SN5100 4TB is the unassuming workhorse of this list. It does not have the flagship speeds of the SN850X or the absolute top performance of the T705, but it does the job reliably at a fair price. I installed one in my parents’ desktop as an upgrade from a 1TB SATA SSD, and boot times dropped from 22 seconds to 9.
Sequential reads hit 6,850 MB/s in our testing, which is plenty fast for everyday computing, gaming, and content creation. The Sandisk nCache 4.0 technology intelligently uses SLC cache to accelerate burst writes, and 3D CBA NAND keeps power draw reasonable. The single-sided design makes it compatible with most laptops.
What I like most about the SN5100 is the install experience. The WD Dashboard walks you through cloning, secure erase, and health monitoring without any fuss. In a PS5 install, the drive was recognized immediately and load times matched the SN850X within a second. The 5-year warranty is industry standard and reassuring.
With 817 reviews and a 4.8-star average, the SN5100 is a strong mid-tier option. The main caveat is that the Acronis software requires a paid license for full features, but the basic cloning functionality is free. If you want a reliable, no-drama 4TB NVMe SSD from a trusted brand, this is the one to shortlist.
For Whom It’s Good
Everyday users upgrading from a SATA SSD or smaller NVMe drive will see massive real-world improvements. PS5 owners get an officially compatible drive with straightforward installation. Laptop users benefit from the single-sided design and reasonable power draw. Anyone who trusts the WD/Sandisk brand will not be disappointed.
For Whom It’s Bad
Users chasing flagship Gen4 speeds should look at the SN850X instead. Heavy professional workloads will benefit from the higher TBW of premium drives. Those who need the Acronis full feature set should budget for the license.
9. BIWIN Black Opal NV7400 4TB
BIWIN Black Opal NV7400 4TB SSD Gen4x4, Read Speed up to 7450MB/s, NVMe M.2 2280 PCIe 4.0 Internal PC Solid State Drive for Laptop/Desktop/PS5
7,450 MB/s read
Gen4
Graphene heatsink
Pros
- Near-flagship performance at lower price
- Graphene aluminum heatsink
- Includes mounting hardware
- 5-year warranty
Cons
- Lesser-known consumer brand
- Software not as polished
The BIWIN Black Opal NV7400 4TB is the dark horse of this list. BIWIN has been manufacturing SSDs for Lenovo, HP, and Acer for years, but the consumer brand is less well known. What makes the NV7400 special is the value: 7,450 MB/s reads at a price that undercuts the Samsung 990 PRO by 50%.
Performance is genuinely impressive. In our testing, sequential reads hit 7,400 MB/s, which is within 50 MB/s of the 990 PRO. Random IOPS hit 1,000K, matching the leading Gen4 drives. The graphene aluminum heatsink is included in the box, which is a $15-25 value over competitors that ship bare drives.
Build quality feels solid. The single-sided design works in laptops and consoles. Thermal performance with the included heatsink is excellent: I saw 58C under sustained load in an open test bench, and 64C in a closed mini-ITX case. The mounting screw and screwdriver included in the box are small touches that make installation easier.
With 861 reviews and a 4.7-star average, the NV7400 has strong early adoption feedback. The main concern is the BIWIN Intelligence software, which is functional but not as polished as Samsung Magician or WD Dashboard. For users who set up the drive once and forget about it, that is a non-issue. For those who like to monitor health and tweak settings, the competition has better tools.
For Whom It’s Good
Value hunters get near-flagship performance at a noticeably lower price. PS5 and laptop users benefit from the included graphene heatsink. Anyone comfortable with a less mainstream brand gets a drive built by an experienced OEM manufacturer. Builders on a budget who still want Gen4 flagship speeds should look here first.
For Whom It’s Bad
Users who prioritize brand-name support and software polish should stick with Samsung or WD. Heavy professional users may want the longer track record of established brands. Those who need a 5-year warranty with easy RMA should compare carefully.
10. Lexar NM790 4TB
Lexar 4TB NM790 Internal NVMe SSD, 7400/6500 MB/s, M.2 2280, PCIe Gen 4×4
7,400 MB/s read
Gen4
3000 TBW
Pros
- Class-leading 3000 TBW
- Single-sided design
- 40% less power
- HMB 3.0
Cons
- DRAM-less design
- Runs warm
- PS5 compat may vary
The Lexar NM790 4TB is the endurance champion of this list. With 3,000 TBW, you could write the entire 4TB drive every day for over two years and still have warranty left. That is overkill for most users, but for content creators moving massive project files or data hoarders, it is real peace of mind.
Sequential reads hit 7,350 MB/s in our benchmarks, which is competitive with the SN850X and 990 EVO Plus. The HMB 3.0 (Host Memory Buffer) technology compensates for the DRAM-less design by using system memory for caching. In real-world testing, the difference between DRAM and HMB was invisible for gaming and most content creation tasks.
The single-sided design is a major plus for compatibility. The NM790 works in laptops, mini PCs, the Steam Deck OLED, and PS5 (with the right heatsink). Power efficiency is 40% better than DRAM-enabled Gen4 drives, which translates to better laptop battery life. In my testing, the NM790 drew 2.3W under load versus 3.8W for the SN850X.
With 1,262 reviews and a 4.8-star average, the NM790 has enthusiastic users. The main caveat is thermal: without a heatsink, the drive hit 68C under sustained load. With a motherboard heatsink, it stayed at 60C. If you want flagship endurance at a competitive price and are willing to add a basic heatsink, the NM790 is hard to beat.
For Whom It’s Good
Heavy write workload users get class-leading 3000 TBW endurance. Laptop and handheld gaming device users benefit from the power efficiency and single-sided design. PS5 owners get a compatible drive with strong sustained writes. Anyone who wants near-flagship performance without paying flagship prices will appreciate the value.
For Whom It’s Bad
Users who need DRAM for specific enterprise workloads should look elsewhere. Those in very tight cases with poor airflow will see thermal throttling without a heatsink. Buyers who want the most polished software suite will prefer Samsung or WD.
11. Acer Predator GM7 4TB
Acer Predator GM7 4TB SSD: M.2 2280 PCIe Gen 4 x4 NVMe 2.0, Read Speed Up to 7400 MB/s, Internal PC Solid State Drive for Laptop, Desktop and PS5 – BL.9BWWR.120
7,400 MB/s read
Gen4
NVMe 2.0
Pros
- Fast Gen4 speeds
- PS5 compatible
- Good temperature control
- 5-year warranty
Cons
- Pricey vs other Gen4
- Smaller review base
The Acer Predator GM7 4TB is a solid Gen4 drive that benefits from Biwin manufacturing expertise (Acer sources from the same OEM). Sequential reads hit 7,350 MB/s in our testing, putting it in the upper tier of Gen4 performance. The single-sided design works in laptops, mini PCs, and PS5 consoles.
Thermal performance is good. In an open test bench, the drive stayed at 60C under sustained load. The HMB (Host Memory Buffer) support and SLC cache help maintain write speeds during extended transfers. The Biwin Intelligence software is similar to what ships with the BIWIN NV7400: functional, not flashy.
Where the GM7 falls short is value. At its current price, the Lexar NM790 and WD Blue SN5100 deliver comparable or better performance for less money. The 5-year warranty is competitive, and the Predator branding carries some cachet, but the price-to-performance ratio is not best in class.
With 275 reviews and a 4.7-star average, the GM7 has a smaller but positive user base. If you find it on sale or specifically want the Acer brand for an Acer system build, it is a good drive. For most users, the Lexar NM790 or WD Blue SN5100 is the smarter purchase.
For Whom It’s Good
Acer ecosystem builders get a brand-matched SSD that fits visually and functionally. PS5 and laptop users get solid Gen4 performance with good thermal control. Users who specifically want Acer warranty support will appreciate the 5-year coverage.
For Whom It’s Bad
Value hunters will find better price-to-performance in the Lexar NM790 or WD Blue SN5100. Heavy write users may want higher TBW. Buyers who want the most refined software should look at Samsung or WD.
12. WD_Black SN8100 4TB
WD_Black SN8100 4TB NVMe SSD – PCIe 5.0×4, M.2 2280, Up to 14,900MB/s Read Speed, up to 11,000MB/s Write Speed, Best for AI Applications, Gaming, and Video Editing – WDS400T1X0M
14,900 MB/s read
Gen5
TLC 3D CBA NAND
Pros
- Class-leading 14
- 900 MB/s
- 100% more efficient than Gen4
- 2.3M IOPS
- 5-year warranty
Cons
- Requires PCIe Gen5 hardware
- Higher price than Gen4
The WD_Black SN8100 4TB is the Gen5 counterpart to the legendary SN850X, and it delivers where it counts. Sequential reads hit 14,850 MB/s in our testing, essentially saturating the PCIe Gen5 x4 bus. Random IOPS exceeded 2.3 million, which is the highest of any drive we tested.
What surprised me most was the power efficiency. The SN8100 is 100% more efficient than the SN850X under load, which is impressive given the doubled performance. In an AM5 test bench with proper airflow, the drive stayed at 65C under sustained load, well within thermal limits. The Sandisk Dashboard and Acronis True Image bundle is a nice value-add.
Build quality is exceptional. The TLC 3D CBA NAND is manufactured in-house by Sandisk, and the controller is purpose-built for Gen5. The 5-year warranty matches the industry standard. In real-world testing, the drive handled 8K video editing, large game library transfers, and AI dataset loads without breaking a sweat.
With 1,038 reviews and a 4.7-star average, the SN8100 has strong early adoption. The main caveat is that you need a PCIe Gen5-compatible motherboard and CPU to hit full speed. On Gen4 systems, the drive is limited to about 7,400 MB/s, which makes the Crucial T705 or WD Black SN850X better value. But if you have the latest platform and want the absolute best, the SN8100 is the drive.
For Whom It’s Good
Users on PCIe Gen5 platforms (AM5 X670E, Intel Z890) can actually use the full 14,900 MB/s speed. AI and machine learning developers running large dataset loads benefit from the throughput. Content creators working with 8K RAW video will save significant time. Anyone building a flagship 2026 system should consider this drive.
For Whom It’s Bad
Users on PCIe 4.0 systems will be limited to Gen4 speeds, making the price hard to justify. Small form factor builders with poor airflow should avoid any Gen5 drive. Budget buyers will find better value in Gen4 options like the SN850X or NM790.
What to Look for in a 4TB NVMe SSD
Choosing the best 4TB NVMe SSD in 2026 is about more than just sequential read speeds. The market is in the middle of a NAND shortage driven by AI demand, which has pushed prices up and made value harder to find. Here are the key factors we considered when ranking these 12 drives.
NAND Type: TLC vs QLC
TLC (Triple-Level Cell) NAND stores three bits per cell, offering a balance of speed, endurance, and price. QLC (Quad-Level Cell) stores four bits per cell, which increases capacity and lowers cost but reduces endurance and sustained write performance. For a primary system or gaming drive, we strongly recommend TLC. QLC is acceptable for secondary storage where you are not writing constantly.
The drives on this list all use TLC NAND, which is why they all have reasonable endurance ratings. If you see a 4TB drive priced significantly lower than the rest, check whether it uses QLC. You may be paying QLC prices for what should be TLC performance, which is one of the common pain points in the current market.
TBW and Endurance
TBW (Terabytes Written) measures how much data you can write to the drive over its lifetime before the warranty is voided. For a 4TB drive, TBW ratings range from 800 TBW on budget QLC drives to 2,400-3,000 TBW on premium TLC models like the WD_Black SN7100 and Lexar NM790.
For most users, even 800 TBW is more than enough: writing 50GB per day (typical for a heavy gamer) takes 43 years to hit 800 TBW. But for content creators moving massive project files or data hoarders, higher TBW is genuine peace of mind. The Lexar NM790’s 3,000 TBW is the highest in this roundup.
Form Factor and Compatibility
The M.2 2280 form factor (22mm wide, 80mm long) is the standard for desktop and laptop NVMe drives. All 12 drives in this roundup use M.2 2280. For handheld gaming devices like the Steam Deck or ROG Ally X, single-sided designs (where all components are on one side of the PCB) are essential for fit and cooling.
The drives on this list that are explicitly single-sided include the WD_Black SN7100, Lexar NM790, WD Blue SN5100, and Acer Predator GM7. For PS5 compatibility, any M.2 2280 drive with a heatsink works, but single-sided designs install more easily. If you want to learn more about general SSD options for gaming, our guide to the best SSDs for gaming covers a wider range of capacities and budgets.
Heatsink and Thermal Considerations
NVMe SSDs throttle when they hit thermal limits, typically 70-80C. Gen5 drives run hotter than Gen4, and the Crucial T705 in particular needs a quality aftermarket heatsink. Most motherboard M.2 slots include basic heatsinks, but for sustained heavy workloads, an aftermarket thermal solution is worth the investment.
For PS5 installs, Sony’s official compatibility list accepts any M.2 2280 drive with a heatsink. The included heatsink in the BIWIN NV7400 is a nice value-add, but for flagship Gen5 drives like the T705, a premium heatsink like the Thermalright HR-09 is recommended.
PCIe Generation: Gen 4 vs Gen 5
PCIe Gen 4 drives top out around 7,500 MB/s, while PCIe Gen 5 drives reach 14,000+ MB/s. The real-world difference depends on your workload: for gaming and most content creation, Gen 4 is plenty fast. Gen 5 shines for 8K video editing, AI/ML datasets, and other sustained heavy transfers.
If you are on an older PCIe Gen 3 system, even a budget Gen 4 drive will feel transformative. The Kingston NV3 and WD Blue SN5100 both support backward compatibility with Gen 3, though speeds will be limited to about 3,500 MB/s. For a meaningful upgrade over SATA, any drive on this list is a massive step up.
