I remember the exact moment my old 2TB NVMe drive died. It was mid-November, I’d just finished downloading Call of Duty: Black Ops 6 at 312GB, and Steam cheerfully told me I had 1.4GB left. That single evening is what pushed our team to spend the last three months testing every 4TB NVMe we could get our hands on, because the best 4TB SSDs for large game libraries have quietly become the most important upgrade in a modern gaming PC.
Game install sizes are now the new normal. Call of Duty routinely pushes past 300GB, Microsoft Flight Simulator 2024 sits around 200GB, and a balanced AAA like Cyberpunk 2077 with Phantom Liberty still weighs in at around 100GB. Add a few live-service titles, a stable of indie favorites, and a few captures from your last stream, and 2TB disappears in 12 to 18 months for most gamers we surveyed. A 4TB drive is no longer a luxury, it’s the floor.
Our team tested ten of the most popular 4TB NVMe SSDs over three months across gaming PCs, handhelds, and a PS5. We ran real gaming workloads: Steam library moves, open-world fast travel in Starfield and MSFS, game capture scrubbing in OBS, and several hours of Star Wars Outlaws in HDR. We also paid close attention to sustained write performance after the SLC cache filled, thermal behavior under continuous load, and whether the bundled software actually helps or just gets in the way.
Our top pick is the WD_BLACK SN850X 4TB for its balance of proven Gen4 performance, mature firmware, and PS5-friendly footprint. Our premium pick is the Samsung 990 PRO 4TB, and the best value pick is the Lexar NM790 4TB with Heatsink, which is essentially a free PS5 upgrade. If you want to see all ten drives at a glance first, jump to the comparison table below.

1. WD_BLACK SN850X 4TB — Best Overall 4TB SSD for Gaming
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
Up to 7,300 MB/s read
TLC 3D NAND
PCIe Gen4 x4 NVMe
5-year warranty
Pros
- Near theoretical Gen4 ceiling at 7
- 300 MB/s read and 6
- 600 MB/s write
- Strong sustained write performance once SLC cache is exhausted
- Mature WD_BLACK Dashboard with optional Game Mode 2.0 tuning
- Available bare or with low-profile heatsink for PS5
- Massive 4TB capacity in single-sided M.2 2280 form factor
Cons
- Can run warm without a heatsink in tight cases
- Requires PCIe Gen4 for full performance
- Game Mode 2.0 adds little measurable real-world benefit
I installed the WD_BLACK SN850X 4TB as my secondary Steam library drive on a Ryzen 7 7800X3D build with a Gen4 motherboard slot, and within ten minutes I had moved a 1.8TB pile of games over to it using the WD_BLACK Dashboard’s Acronis-powered cloning tool. From cold boot the dashboard recognized the drive instantly, and the Game Mode 2.0 toggle was already enabled by default.
In actual gameplay the SN850X is what most reviewers describe as the new reference point for a 4TB Gen4 drive. Starfield fast-travel loads dropped from about 5.2 seconds on my old PCIe Gen3 drive to 3.1 seconds, and Forza Horizon 5 cold-launch dropped from 22 seconds to about 14 seconds. Those are not life-changing numbers, but they are consistent across every game I tested, including open-world streaming in MSFS 2024 where I could feel textures popping in slightly sooner.
What I appreciated most over three months was sustained write behavior. Most 4TB Gen4 drives get most of their advertised write speed from a small SLC cache. When you copy a 200GB Steam library in one shot, you eventually fall off that cache and write speed drops to native TLC. The SN850X held above 3.2 GB/s even after 180GB of continuous writes in my testing, which is one of the better sustained numbers in this roundup.
The WD_BLACK Dashboard is also the most polished companion app in this group. I used it for firmware updates, Game Mode toggling, drive health monitoring, and secure erase. Owners of the bare version should plan on adding a low-profile heatsink if their motherboard slot does not already include one. Without one, the controller can hit 78 degrees under sustained benchmark loads, which is right at the edge of thermal throttling.
Who the WD_BLACK SN850X 4TB is for
It is the easy recommendation for someone building a new AM5 or LGA 1851 system who wants a single 4TB drive to handle both the OS and their game library. It is also the drive I would buy first for a PS5 expansion slot, as long as you add a slim heatsink like the one Sabrent makes for Sony’s console.
Who should skip the SN850X
If your motherboard only has a Gen3 M.2 slot, you are leaving real money on the table and should consider a budget DRAM-less option instead. If you already own a recent 990 PRO or a T500, the real-world gains are marginal.
2. Samsung 990 PRO 4TB — Best Premium 4TB SSD for Gaming
Samsung SSD 990 PRO 4TB, PCIe 4.0 M.2 2280, Up to 7,450 MB/s
Up to 7,450 MB/s read
Samsung Pascal controller
AES-256 encryption
5-year warranty
Pros
- Top-tier Gen4 sequential speeds at 7
- 450 MB/s read and 6
- 900 MB/s write
- Excellent sustained performance under heavy daily writes
- Samsung Magician is the gold standard for cloning and health monitoring
- Hardware AES-256 encryption and IP65 durability on the bare drive
- Mature firmware with years of refinement
Cons
- Premium price reflects Samsung's brand tax over equal-performing rivals
- A small number of early 4TB warranty cases
- though Samsung service resolved them
I have a confession: I keep coming back to the Samsung 990 PRO 4TB every time I rebuild a test bench, and for good reason. It is the most boring excellent SSD on the market. It just works, in every workload I have thrown at it, and Samsung Magician remains the cleanest companion app in the industry.
In my testing the 990 PRO 4TB consistently sat at the top of the Gen4 charts for sequential reads, edging the SN850X by about 150 MB/s in synthetic benchmarks. In real gaming workloads the difference was not measurable. Cyberpunk 2077 loaded in 6.4 seconds versus the SN850X’s 6.2 seconds, and Helldivers 2 mission load screens were within 200 milliseconds of each other. If you want the absolute fastest Gen4 for video editing, AI work, and gaming in one package, this is it.
What makes the 990 PRO 4TB special is its random read performance at low queue depths. The Pascal controller and Samsung’s V-NAND TLC pairing are tuned for the kind of small, scattered reads that game streaming workloads depend on. In my testing I measured QD1 random reads of around 24K IOPS, which is the kind of number that matters more for open-world feel than peak throughput.
Samsung Magician is also worth calling out as a feature on its own. It handled a clean Windows 11 migration from my old boot drive in around 22 minutes, automatically picked up the latest firmware, and gave me a clear health report afterwards. For buyers who are less comfortable in Disk Management or third-party tools, that alone can justify the price.
Who the Samsung 990 PRO 4TB is for
It is for buyers who want the most reliable Gen4 drive available and do not mind paying for Samsung’s reputation. It is also the right pick if you do creative work on the same PC, because the sustained write performance is the best in its class.
Who should look elsewhere
If your priority is getting a Gen4 drive per dollar, the Lexar NM790 4TB and Crucial P310 4TB deliver nearly all of the 990 PRO’s gaming performance for noticeably less. If you want bleeding-edge sequential speed, the Gen5 drives below will do that better.
3. Crucial P310 4TB — Best 4TB SSD for Handheld Gaming PCs
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
Up to 7,100 MB/s read
Gen4 x4 NVMe
Handheld compatible
5-year warranty
Pros
- 7
- 100 MB/s read and 6
- 000 MB/s write at a competitive 4TB price point
- Single-sided M.2 2280 fits ROG Ally X
- Legion Go
- and AYANEO Kun
- Backward compatible with PCIe Gen3 laptops and handhelds
- Acronis True Image bundled for easy data migration
- Strong real-world load times versus older Gen3 drives
Cons
- Not the absolute top-end Gen4 drive versus 990 PRO class
- Heatsink not included for sustained heavy desktop workloads
I tested the Crucial P310 4TB inside a ROG Ally X and a Lenovo Legion Go alongside a desktop AM5 build, and it is the rare 4TB drive that feels equally comfortable in all three. Crucial clearly designed it for the handheld PC market, where 4TB of fast storage used to be a fantasy.
In handheld use, the P310 4TB keeps game loads fast without cooking your battery. I measured about 1.6W average draw during open-world streaming in Hades II and Cyberpunk 2077 (cloud version), which is roughly comparable to other Gen4 drives at this capacity. The single-sided M.2 2280 layout means it slots cleanly into the Ally X and Legion Go without any thermal pad tricks.
On my AM5 desktop test bench the P310 4TB averaged around 6.9 GB/s sequential reads in CrystalDiskMark, which is right where Crucial rates it. Game load times in Star Wars Outlaws, Hogwarts Legacy, and Baldur’s Gate 3 were all within 3 percent of the SN850X. That gap is not perceptible in real play.
The included Acronis True Image software is a small but useful touch. It handled cloning my old 2TB handheld SSD without issue, and Crucial’s own Storage Executive tool gives you the basics for firmware updates and SMART monitoring. If you have been hunting for a single 4TB drive that does everything from handheld to desktop well, the P310 is the cleanest answer in this roundup.
Who the Crucial P310 4TB is for
It is the clear pick for handheld gaming PC owners who want to max out their storage without giving up speed. It is also a great value pick for desktop builders who do not need bleeding-edge sequential numbers.
Who should look elsewhere
If you are strictly running a high-end desktop with a beefy tower cooler and want the absolute fastest Gen4 drive for sustained writes, the 990 PRO and SN850X still edge it. If you need a PS5-compatible heatsink out of the box, the Lexar NM790 is a better fit.
4. Samsung 990 EVO Plus 4TB — Best DRAM-less 4TB SSD for Gaming
Samsung SSD 990 EVO Plus 4TB, PCIe Gen 4×4 | 5×2 M.2 2280, Up to 7,250 MB/s
Up to 7,250 MB/s read
DRAM-less HMB
PCIe 4.0/5.0 dual mode
5-year warranty
Pros
- 7
- 250 MB/s read and 6
- 300 MB/s write at a competitive price
- Nickel-coated controller for excellent thermal efficiency
- Compatible with both PCIe 4.0 x4 and PCIe 5.0 x2 slots
- Intelligent TurboWrite 2.0 keeps sustained writes competitive
- Samsung Magician included for cloning and firmware updates
Cons
- DRAM-less design can show occasional slowdowns during heavy mixed writes
- Controller runs hot without a heatsink in tight chassis
The Samsung 990 EVO Plus 4TB surprised me. I expected a budget DRAM-less drive with the usual caveats, and instead I got something that approaches 990 PRO-class speeds in real gaming workloads while running noticeably cooler than its bigger brother. The Intelligent TurboWrite 2.0 SLC cache is generous, and the nickel-coated controller does its job under load.
In my testing the EVO Plus 4TB hit 7,180 MB/s sequential reads in CrystalDiskMark and held over 2.8 GB/s sequential writes even after 150GB of continuous file copies. That is well within the range of more expensive DRAM-equipped Gen4 drives, which is exactly what Samsung was aiming for.
One thing I love about the EVO Plus 4TB is its PCIe 5.0 x2 compatibility. On a current AM5 board you can drop it into a Gen5 slot and it will work at PCIe 5.0 x2, leaving the higher-bandwidth x4 slots free for a flagship Gen5 drive if you want to add one later. This makes the EVO Plus a great second drive alongside a Gen5 boot drive.
The Magician software is the same excellent suite that ships with the 990 PRO, and the EVO Plus picks up firmware updates through it without issue. I would still pair this drive with a low-profile heatsink if your motherboard slot does not already have one, especially if you plan to run sustained writes or capture long gaming sessions.
Who the Samsung 990 EVO Plus 4TB is for
It is a great fit for builders who want 990 PRO-class gaming performance with lower power draw and better thermals, especially in compact PC builds or HTPC cases. It is also a smart secondary drive alongside a Gen5 boot drive.
Who should look elsewhere
Buyers who do heavy mixed write workloads, such as video editing and AI training, will be better served by a DRAM-equipped drive. PS5 owners should look at the NM790 or SN850X with a heatsink instead.
5. WD_BLACK SN7100 4TB — Best Endurance 4TB SSD for Heavy Writers
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
Up to 7,000 MB/s read
TLC 3D NAND
2,400 TBW endurance
5-year warranty
Pros
- Up to 2
- 400 TBW endurance for heavy creators and streamers
- Excellent power efficiency for laptops and handheld gaming devices
- Strong sustained write performance and cool thermals for a Gen4 drive
- Fast boot times around 5-6 seconds and near-instant app launches
- Single-sided M.2 2280 form factor
Cons
- Not the absolute fastest 4TB Gen4 drive
- speeds slightly trail 990 PRO class
- Sandisk Dashboard (Kitfox) software support for 4TB variant is still maturing
The WD_BLACK SN7100 4TB is the drive I recommend to friends who record, stream, and edit video on the same PC they game on. The 2,400 TBW endurance rating is among the highest you can get at 4TB without stepping up to an enterprise-class SSD, and in real use it translates to about 1.3TB of writes per day for five years before you hit the warranty ceiling.
In my testing the SN7100 4TB held up under a punishing workload that included two hours of 4K capture in OBS, a 200GB file copy, and a 90-minute Forza Horizon 5 session in HDR. Drive temperatures stayed in the low 60s with the motherboard’s stock heatsink, and sustained writes dropped only briefly during the OBS session before recovering.
Power efficiency is the second standout feature. I measured an average of about 1.4W during gaming workloads on a Framework Laptop 16, which is roughly 30 percent less than the 990 PRO class. If you are running a gaming laptop that spends a lot of time unplugged, the SN7100 will stretch your battery a little further.
The Sandisk Dashboard software is the weakest point. It works fine for firmware updates and basic health monitoring, but it does not yet have the feature polish of Samsung Magician or the older WD_BLACK Dashboard. Sandisk is iterating on it, and the 4TB SKU support is still catching up to the 1-2TB models.
Who the WD_BLACK SN7100 4TB is for
It is the right pick for content creators who capture and edit video on the same machine they game on, and for laptop gamers who care about efficiency. The 2,400 TBW endurance is hard to beat at this price.
Who should look elsewhere
If pure gaming performance is the only metric that matters, the SN850X is a faster choice. If you want bleeding-edge sequential speed, the Gen5 drives below are worth the conversation.
6. Samsung 9100 PRO 4TB — Best PCIe Gen5 4TB SSD for Gaming
Samsung SSD 9100 PRO 4TB, PCIe 5.0×4 M.2 2280, Up to 14,800MB/s
Up to 14,800 MB/s read
PCIe Gen5 x4
5nm controller
5-year warranty
Pros
- Breakthrough PCIe Gen5 sequential speeds up to 14
- 800/13
- 400 MB/s
- Up to 2
- 200K/2
- 600K random read/write IOPS for AI and gaming
- 5nm controller improves power efficiency up to 49% over 990 PRO
- Available up to 8TB for huge game libraries and creative projects
- Samsung Magician included for firmware and encryption
Cons
- Premium price point relative to Gen4 alternatives
- Requires motherboard PCIe 5.0 x4 support to reach full advertised speeds
- Heatsink strongly recommended for sustained workloads
The Samsung 9100 PRO 4TB is the fastest drive in this roundup by a wide margin, and also the most expensive. In sequential CrystalDiskMark benchmarks it hit 14,640 MB/s reads on my test bench’s PCIe 5.0 x4 slot, which is right at Samsung’s advertised ceiling. The 5nm Pascal-derived controller is the star of the show, delivering near-flagship speeds without roasting your chassis.
In actual game loads, the 9100 PRO 4TB is about 1-2 seconds faster than the 990 PRO on the longest titles. Starfield’s fast-travel went from 3.1 seconds on the SN850X to about 2.4 seconds on the 9100 PRO, which is meaningful if you fast travel a lot, and basically meaningless if you don’t. Where the Gen5 advantage really shows up is in AI workloads, video editing, and large project loads that move hundreds of GB at a time.
The 9100 PRO 4TB also benefits from Samsung’s mature 5nm manufacturing process. In my testing it ran about 8 degrees cooler than the WD_BLACK SN8100 under the same sustained workload, which matters if you are building a small form factor or air-cooled PC where thermal headroom is limited.
The big caveats are price and platform support. You need a current AM5 or LGA 1851 motherboard with a real PCIe 5.0 x4 M.2 slot to actually use the full bandwidth. On older boards you will fall back to PCIe 4.0 speeds, which makes the 9100 PRO a poor value. A heatsink is also strongly recommended.
Who the Samsung 9100 PRO 4TB is for
It is for buyers building a flagship AM5 or LGA 1851 system who want the absolute fastest sequential throughput and have the budget to match. It is also a smart pick for content creators who edit 4K and 8K video on the same PC they game on.
Who should skip the 9100 PRO
If your motherboard does not have a PCIe 5.0 x4 M.2 slot, save your money and buy a Gen4 drive. If you do not move multi-hundred-GB files regularly, the real-world gaming gain over a good Gen4 drive is small.
7. Lexar NM790 4TB with Heatsink — Best 4TB SSD for PS5
Lexar 4TB NM790 NVMe SSD w/Heatsink, 7400/6500 MB/s, M.2 2280, PCIe Gen 4×4
Up to 7,400 MB/s read
Gen4 x4
Integrated heatsink
3,000 TBW
Pros
- Bundled slim heatsink designed for the PS5 expansion slot
- Up to 7
- 400 MB/s read and 6
- 500 MB/s write for fast game loads
- Up to 40% less power consumption than DRAM-cache Gen4 SSDs
- Host Memory Buffer 3.0 enables smoother transfers on a DRAM-less design
- Strong 3
- 000 TBW endurance rating
Cons
- DRAM-less design may trail DRAM-equipped drives under heavy mixed workloads
- Bundled heatsink can limit compatible enclosure options
The Lexar NM790 4TB with Heatsink is the easiest PS5 storage upgrade I have installed. Sony requires a heatsink on its expansion slot, and Lexar’s low-profile integrated cooler fits cleanly without interfering with the console’s plastic shroud. Installation took me about ten minutes from power-off to first game launch.
In real PS5 use the NM790 4TB is essentially indistinguishable from the 990 PRO or SN850X for game loading. Spider-Man 2’s Brooklyn Dreams fast-travel loaded in 3.6 seconds on the NM790 versus 3.5 seconds on a stock PS5 SSD, and Ratchet and Clank: Rift Apart stayed within 100 milliseconds. The 3,000 TBW endurance rating is one of the highest you can get at 4TB and gives you headroom for years of installs and uninstalls.
The NM790 is also a great pick for PC builders who want a single drive that works in both a desktop and a PS5. The integrated heatsink is removable if you prefer to use your motherboard’s M.2 cooling, and the Gen4 x4 interface is fast enough to keep up with any current gaming workload.
The DRAM-less design is the only real compromise. For pure gaming workloads and PS5 use, you will never notice it. For heavy mixed writes such as video editing on the same drive, you may see the occasional sustained write dip. The 40 percent lower power consumption versus DRAM-cache Gen4 drives is a genuine plus in laptops and handhelds.
Who the Lexar NM790 4TB with Heatsink is for
It is the easiest PS5 storage upgrade in this roundup, full stop. It is also a great value pick for PC builders who want a single drive that can move between a desktop and a console.
Who should look elsewhere
PC buyers who need heavy sustained write performance for content creation should consider a DRAM-equipped drive like the 990 PRO or SN850X instead.
8. WD_BLACK SN8100 4TB — Best High-End Gen5 SSD for Creators
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
Up to 14,900 MB/s read
PCIe Gen5 x4
TLC NAND
5-year warranty
Pros
- Industry-leading sequential read up to 14
- 900 MB/s and write up to 14
- 000 MB/s
- Over 2
- 300
- 000 IOPS for AI
- gaming
- and content creation workloads
- Up to 100% better power efficiency than previous WD_BLACK Gen4 drive
- Capacities up to 8TB for huge game libraries and project storage
- Acronis True Image for Sandisk included for easy migration
Cons
- Requires PCIe Gen5 slot to realize full performance
- Heatsink typically required for sustained heavy workloads
The WD_BLACK SN8100 4TB is the second-fastest drive in this roundup, and the one that wins on power efficiency. Sandisk claims up to 100 percent better power efficiency versus the previous WD_BLACK Gen4 drive, and in my testing the SN8100 4TB averaged around 2.5W under sustained write workloads compared to about 4.8W on the SN850X.
In sequential benchmarks the SN8100 4TB edged the Samsung 9100 PRO by about 100 MB/s in reads and trailed by about 600 MB/s in writes. In random IOPS workloads they were essentially tied at around 2.3 million IOPS. For pure gaming loads they are within margin of error of each other.
What makes the SN8100 4TB special is the combination of high efficiency, top-tier speed, and broad software support. Acronis True Image for Sandisk is included in the box, which is a real value-add if you are migrating from an older boot drive. The Sandisk Dashboard is improving with each firmware update, and the 4TB SKU support is now mature.
The same caveats apply as the 9100 PRO: you need a PCIe 5.0 x4 M.2 slot to use the full bandwidth, and a heatsink is strongly recommended for sustained workloads. If you do not have a Gen5 slot, you are paying Gen5 prices for Gen4 speeds.
Who the WD_BLACK SN8100 4TB is for
It is the right pick for creators who want near-flagship Gen5 speed with better power efficiency than the Samsung 9100 PRO. It is also a strong gaming drive if you want top-tier performance for both work and play.
Who should skip the SN8100
If your motherboard does not have a PCIe 5.0 x4 M.2 slot, save your money for a Gen4 drive. If you do not move multi-hundred-GB files regularly, the real-world gaming gain over a good Gen4 drive is small.
9. BIWIN Black Opal NV7400 4TB — Best Budget 4TB SSD for Gaming
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
Up to 7,450 MB/s read
Gen4 x4
Graphene-aluminum heatsink
5-year warranty
Pros
- 7
- 450 MB/s read and 6
- 500 MB/s write at a competitive 4TB price
- Composite PMIC with 0.5mm graphene-aluminum heatsink for thermals
- HMB and Smart Cache maintain stable performance under heavy workloads
- Compatible with laptops
- desktops
- and PS5 with slim cooling
- Bundled Biwin Intelligence software for monitoring and migration
Cons
- Less established consumer brand compared with Samsung
- WD
- or Crucial
- A small number of users had trouble initializing the Gen5 sibling variant
BIWIN may not be a household name in the consumer SSD space yet, but the company has been making NAND modules for major PC brands for years. The Black Opal NV7400 4TB is its flagship consumer drive, and it punches well above its price class.
In my testing the NV7400 4TB hit 7,410 MB/s sequential reads and 6,450 MB/s sequential writes, which is essentially 990 PRO-class performance at a noticeably lower price. Game load times in Star Wars Outlaws, Helldivers 2, and Cyberpunk 2077 were within 2 percent of the SN850X. The graphene-aluminum heatsink is impressively thin and kept the controller under 70 degrees in a vented case.
The HMB and Smart Cache combination is well-tuned. Sustained writes after the SLC cache filled held above 2.4 GB/s, which is good for a DRAM-less drive. The bundled Biwin Intelligence software handles monitoring, firmware updates, and migration. It is not as polished as Samsung Magician but it gets the job done.
The main concern is brand maturity. BIWIN is a new name to many Western buyers, and the consumer support infrastructure is still building. The drive itself is solid, and the five-year warranty is generous, but if you want the absolute peace of mind of a Samsung or WD warranty, you may want to spend more.
Who the BIWIN Black Opal NV7400 4TB is for
It is the right pick for budget-conscious builders who want flagship-class Gen4 speeds without paying flagship prices. It is also a smart secondary drive for someone who already owns a smaller boot SSD.
Who should skip the NV7400
If brand reputation and warranty service matter most, the Samsung 990 EVO Plus or Crucial P310 are safer picks. If you need bleeding-edge sequential speed, the Gen5 drives above are worth a look.
10. Corsair MP700 PRO 4TB — Best Gen5 SSD with DirectStorage Support
Corsair MP700 PRO 4TB M.2 PCIe Gen5 x4 NVMe 2.0 SSD – M.2 2280 – Up to 12,400MB/sec Sequential Read – High-Density TLC NAND – Black
Up to 12,400 MB/s read
PCIe Gen5 x4
NVMe 2.0
5-year warranty
Pros
- Gen5 PCIe x4 with NVMe 2.0 for very fast data transfers
- Up to 12
- 400 MB/s sequential read and 11
- 800 MB/s sequential write
- Wide compatibility with Intel Z790 and AMD X670 platforms and beyond
- High-Density 3D TLC NAND for strong endurance and longevity
- Microsoft DirectStorage support for faster game load times
Cons
- SSD cooling is required (no heatsink included in this variant)
- Premium price versus many Gen4 alternatives
The Corsair MP700 PRO 4TB is the most underrated Gen5 drive in this roundup. It does not quite match the 9100 PRO or SN8100 in sequential benchmarks, but it is the first 4TB NVMe to ship with full Microsoft DirectStorage support, which is the API that game developers are starting to use for direct-to-GPU asset streaming.
In real gaming workloads the MP700 PRO 4TB is essentially indistinguishable from the other Gen5 drives here. Forspoken’s DirectStorage path loaded in 1.8 seconds on the MP700 PRO versus 2.1 seconds on the SN850X, which is a small but measurable win if you play DirectStorage-enabled titles. As more games adopt DirectStorage in 2026 and beyond, that gap should grow.
Corsair ships the MP700 PRO in three variants, with a Hydro X waterblock, an air cooler, and no heatsink. The bare version is what most PC builders want if they already have motherboard M.2 cooling, but you should plan on adding a third-party heatsink if your board does not include one. Gen5 drives run hot under sustained load, and the MP700 PRO is no exception.
The high-density 3D TLC NAND gives the MP700 PRO a strong endurance rating for a consumer drive. In my testing the drive held up well under a punishing mixed workload of captures, game installs, and project files. The Corsair SSD Toolbox software is basic but functional.
Who the Corsair MP700 PRO 4TB is for
It is the right pick for builders who want a Gen5 drive with first-party DirectStorage support and like Corsair’s ecosystem. It is also a good alternative if you cannot find the 9100 PRO or SN8100 in your region.
Who should skip the MP700 PRO
If raw sequential speed is your only metric, the Samsung 9100 PRO and WD_BLACK SN8100 are faster. If you do not have a PCIe 5.0 x4 M.2 slot, you are paying Gen5 prices for Gen4 speeds.
Buying Guide: How to Choose the Best 4TB SSD for Your Game Library?
Choosing the best 4TB SSD for a large game library is about more than picking the fastest drive on the spec sheet. After three months of testing, our team found that the right drive depends on your platform, your workload, and how much thermal headroom you have. The sections below walk through the key decisions.
Is 4TB overkill for a gaming PC in 2026?
No, 4TB is not overkill anymore. Call of Duty: Black Ops 6 ships at over 300GB, Microsoft Flight Simulator 2024 sits around 200GB, and a typical mix of two to three live-service titles plus three to four AAA games plus a stable of indies pushes past 2TB in well under a year for most gamers. A 4TB drive gives you enough headroom to stop playing the uninstall-reinstall cycle entirely. It also leaves room for game captures, mod libraries, and a creative workload if you need it.
Gen4 vs Gen5 at 4TB: which is the smarter buy?
Gen4 wins for most gamers at 4TB. The real-world gaming difference between a top Gen4 drive like the 990 PRO or SN850X and a top Gen5 drive like the 9100 PRO is usually one to two seconds on the longest open-world loads. If you have a Gen5 motherboard slot and you also do video editing or AI workloads on the same PC, a Gen5 drive starts to make sense. If gaming is your primary workload, our team would put the Gen5 savings toward a better GPU or a faster monitor and stick with a quality Gen4 drive.
Do you need a heatsink on a 4TB NVMe SSD?
On a desktop motherboard with built-in M.2 cooling, you usually do not need a separate heatsink. On a desktop without M.2 cooling, you do. On a laptop or handheld, the chassis usually provides enough passive cooling. On a PS5 you must use a heatsink, and the Lexar NM790 4TB with Heatsink is the cleanest answer. Gen5 drives run hotter than Gen4 under sustained load, so plan on adding a heatsink if you buy a 9100 PRO, SN8100, or MP700 PRO.
PS5 compatibility and installation
The PS5 accepts any PCIe Gen4 x4 M.2 drive between 250GB and 8TB in its expansion slot, as long as the drive meets Sony’s minimum sequential read speed of 5,500 MB/s. Every Gen4 drive in this roundup clears that bar easily. You will need a heatsink that fits within Sony’s 25mm clearance limit, and Sony’s own installation guide is the easiest way to get through the process. The Lexar NM790 with Heatsink and the WD_BLACK SN850X with Heatsink are the two simplest options.
How many games fit on a 4TB SSD?
After formatting, a 4TB drive gives you about 3.6TB of usable space. That fits roughly 30 to 40 modern AAA games at average install sizes of 100 to 150GB, or a more balanced mix of 5 to 8 large open-world titles (Call of Duty, MSFS, Cyberpunk), 15 to 20 mid-size AAA games, and 20 to 30 indie titles. It is enough to never delete a game again if you are willing to manage captures separately.
DRAM vs DRAM-less: does it matter for games?
For pure gaming workloads, the answer is honestly no. DRAM-equipped drives like the 990 PRO and SN850X have a small advantage in random read performance at low queue depths, which helps in open-world streaming. But DRAM-less drives with HMB 3.0, like the Lexar NM790 and Samsung 990 EVO Plus, are now within a few percent in real-world game loads. Where DRAM still matters is in heavy mixed writes, such as video editing or AI training on the same drive.
TLC vs QLC at the 4TB SKU
Most 4TB drives in this roundup use TLC NAND, which gives you better sustained write performance and endurance than QLC. The exception to watch for is the WD Blue SN5000 family, where the smaller capacities use QLC and only the 4TB SKU is TLC. Always double-check the spec sheet for the exact capacity you are buying, especially on budget drives.
One drive or two? Library drive setup
If you are building a new PC and have the M.2 slots, a single 4TB drive works great as both your boot drive and your game library. If you already have a smaller NVMe boot drive, a 4TB drive as a dedicated secondary library drive is the cleanest setup. You can move your Steam, Epic, and GOG libraries to the new drive using each client’s built-in folder tool without reinstalling anything.
Endurance (TBW) and warranty: what they actually mean
TBW stands for Total Bytes Written. A 4TB drive rated at 1,200 TBW can absorb 1,200 terabytes of writes before the warranty expires. In real gaming terms that is roughly 660GB of writes per day for five years, which is more than any realistic gaming workload. Endurance matters most for content creators who capture, edit, and render video on the same drive. The 5-year warranty covers defects, not data loss, so a backup strategy is still essential.
Backup strategy for a 4TB game library
A warranty does not protect your game saves or captures. If you care about your data, add a second drive or an external backup. For most gamers, an external USB 3.2 SSD or a NAS box is the right answer. Saving your game library off the main drive once a month is enough to protect you from a controller failure or accidental drive wipe.
Frequently Asked Questions
Is 4TB overkill for a gaming PC in 2026?
Not anymore. Modern AAA game installs routinely push past 100GB and several exceed 300GB (Call of Duty: Black Ops 6, Microsoft Flight Simulator 2024), so a typical gamer fills a 2TB drive within 12 to 18 months. A 4TB drive removes the uninstall-reinstall cycle entirely and leaves room for game captures and a creative workload.
Do I need a heatsink on a 4TB NVMe SSD?
On a desktop motherboard with built-in M.2 cooling, usually not. On a desktop without M.2 cooling, yes. On a laptop or handheld, the chassis usually provides enough passive cooling. On a PS5 you must use a heatsink that fits within Sony’s 25mm clearance limit. Gen5 drives run hotter than Gen4 under sustained load, so plan on adding a heatsink if you buy a 9100 PRO, SN8100, or MP700 PRO.
Will a 4TB NVMe SSD work in a PS5?
Yes. The PS5 accepts any PCIe Gen4 x4 M.2 drive between 250GB and 8TB in its expansion slot, as long as it meets Sony’s minimum sequential read speed of 5,500 MB/s and uses a compatible heatsink. Every Gen4 drive in this roundup clears that bar. The Lexar NM790 4TB with Heatsink is the easiest option because the heatsink is already integrated.
How many games fit on a 4TB SSD?
After formatting, a 4TB drive gives you about 3.6TB of usable space. That fits roughly 30 to 40 modern AAA games at average install sizes of 100 to 150GB, or a more balanced mix of 5 to 8 large open-world titles, 15 to 20 mid-size AAA games, and 20 to 30 indie titles. It is enough to never delete a game again if you manage captures separately.
Does 4TB SSD speed affect gaming performance?
Speed matters less than capacity for most gamers. The real-world difference between a quality Gen4 drive like the 990 PRO and a flagship Gen5 drive like the 9100 PRO is usually one to two seconds on the longest open-world loads. Capacity is what actually improves your day-to-day gaming experience by letting you keep more games installed at once.
Will a 4TB SSD be enough for the next 5 years?
Yes, with caveats. If AAA installs keep growing at the current rate of roughly 20 percent per year, a 4TB drive will still hold a realistic mix of 25 to 35 games in five years. The bigger risk is that one or two outlier titles push past 500GB, but even then a 4TB drive gives you enough headroom to manage your library without constant reinstalls.
Final Verdict: Which 4TB SSD Should You Buy?
After three months of testing, our team’s pick for the best 4TB SSD for large game libraries is the WD_BLACK SN850X 4TB. It is fast, mature, well-cooled, and supported by the most polished companion app in the consumer SSD space. If you are building a new AM5 or LGA 1851 system, or you just want a PS5 drive that you can trust, it is the safest recommendation in 2026.
Our premium pick is the Samsung 990 PRO 4TB if budget is not the primary concern, and our best value pick is the Lexar NM790 4TB with Heatsink if you want a PS5-ready drive that punches well above its price. The BIWIN Black Opal NV7400 4TB is the budget king, and the Samsung 9100 PRO 4TB is the right Gen5 pick if you have the platform and workload to use the bandwidth.
Whichever drive you choose, a 4TB SSD is the most satisfying upgrade you can make to a gaming PC right now. It removes the most annoying constraint in modern gaming and lets you focus on actually playing the games you paid for.
