If you work with storage-heavy apps or simply want quick access to your entire Steam library, there is no substitute for a high-capacity SSD. Four terabyte SSDs are now commonplace, and 8TB models have become increasingly available in the consumer market.
However, the landscape shifted dramatically in the second half of 2025. Not for the better, unfortunately, as nearly a decade of declining SSD prices is now in reverse. A NAND flash memory shortage driven by AI infrastructure demand has sent prices soaring and created supply constraints that will persist through 2027, making purchase decisions more difficult.
Here, we’ve rounded up the best 4TB SSDs from major manufacturers as of early 2026 based on our own testing and market research. The short version is that most high-end M.2 SSDs now come in a 4TB variety, as do many 2.5″ SATA models.
Fastest Vs. Best Value 4TB & 8TB M.2 SSDs
Cost per GB remains a key factor when buying storage, though the NAND shortage is compressing the traditional price differences between budget and premium tiers. You’ll still pay a premium for PCIe 5.0 capability, which isn’t necessary if your system runs PCIe 4.0.

Released in May 2025, the the WD Black SN8100 is SanDisk’s current flahship Gen5 SSD. It uses a custom Silicon Motion SM2508 controller paired with Kioxia’s 218-layer BiCS8 TLC NAND to deliver exceptional performance while running cooler than competing Phison E26-based drives. It’s one of the fastest consumer SSDs at this time, if not the fastest overall.
For those on PCIe 4.0 systems, the Samsung 990 PRO remains the fastest Gen4 drive we’ve tested. Samsung’s newer 9100 PRO is also one of the few flagship SSDs shipping in an 8TB capacity.
In the value segment, SanDisk is also well positioned with the WD Black SN7100 – one of the best budget Gen4 options. This DRAM-less drive uses Host Memory Buffer (HMB) technology and delivers impressive performance for its price point, making it particularly suitable for laptops and handheld gaming devices.
For Gen5 compatibility, you need a PCI-Express 5.0-capable system (based on e.g. AMD B650/X670 or later, or select Intel Z790 boards or later) with a free M.2 PCIe Gen5 x4 slot.
High-End 4TB M.2 NVMe SSDs
A high-end 4TB M.2 SSD makes an excellent system drive, especially in single-drive configurations. Most flagship SSDs now come in 4TB capacities. Read our comprehensive writeup about the best M.2 drives for detailed information. These drives are market leaders in early 2026:

There are many Gen5 alternatives, but all of the early ones use the same Phison E26 controller. E26-based SSDs tend to run quite hot and require capable cooling solutions. This is less of an issue with newer models like the SN8100, 9100 Pro, Fury Renegade G5, and T710, which use more efficient controllers and run significantly cooler.

Using a high-end Gen4 NVMe SSD as a system drive is still viable in the Gen5 era. You’ll barely notice the difference in normal use, and you’ll definitely notice the pricing difference compared to flagship PCIe 5.0 drives. However, the NAND shortage could further reduce the pricing gaps between Gen4 and Gen5 options going forward.
Best Value 4TB M.2 NVMe SSDs
If you are looking to minimize the cost per GB, without sacrificing too much performance, there are many affordable M.2 SSDs to choose from in the Gen4 space. Most will be based on 4-channel controllers and in some cases cheaper, QLC NAND.
| Name | Sequential read/write (MB/s) | NAND Type | Endurance | Latest Price* | Check Availability |
|
|---|---|---|---|---|---|---|
 | WD Black SN7100 (4TB) | 7000/6700 | TLC | 2,400 TBW/ 5-Year | Price not available | Amazon |
 | Crucial T500 (4TB) | 7000/6900 | TLC | 2,400 TBW/ 5-Year | Price not available | Amazon |
 | Samsung 990 EVO Plus (4TB) | 7250/6300 | TLC | 2,400 TBW/ 5-Year | Price not available | Amazon |
 | Kingston NV3 (4TB) | 6000/5000 | QLC | 1,280 TBW/ 5-Year | Price not available | Amazon |
 | Crucial P3 Plus (4TB) | 4800/4100 | QLC | 800 TBW/ 5-Year | Price not available | Amazon |
The main downside with QLC NAND is its lower durability compared to TLC, yet QLC drives aren’t significantly more affordable in the current market. When you can get solid TLC-based SSDs for similar prices, the choice is easy. Drives like the WD Black SN7100 and Samsung 990 EVO Plus also outperform QLC competitors significantly.
High-Capacity 2.5″ SATA SSDs
If you’re looking for lots of fast internal storage at a more reasonable cost per GB, SATA drives should offer better prices compared to their M.2 PCIe counterparts. However, the NAND shortage has affected SATA pricing as well. For quite some time Samsung was the only manufacturer with 4TB or larger consumer SSDs in the market, but additional options have emerged.
| Name | Max. seq read/write (MB/s) | 4K random read/write (IOPS) | NAND | Endurance rating | Check Price |
|
|---|---|---|---|---|---|---|
 | Samsung 870 EVO (4TB) | 560/530 | 98K/88K | TLC | 2,400 TBW | Amazon |
 | Samsung 870 QVO (4TB) | 560/530 | 98K/88K | QLC | 1,440 TBW | Amazon |
 | WD Red SA500 (4TB) | 560/530 | 95K/82K | TLC | 2,500 TBW | Amazon |
 | WD Blue (4TB) | 560/530 | 95K/82K | TLC | 600 TBW | Amazon |
Sequential performance is fairly similar across the board, which isn’t surprising considering that the SATA interface has been fully utilized by leading SSDs for many years. However, the 2.5″ form factor remains interesting as it offers higher capacities at potentially more attractive prices per GB. It’s also the only alternative if you have no spare M.2 slots, such as in a NAS.
An interesting market development: some large-capacity external SSDs are now selling for less than internal 4TB SATA drives (possibly due to the ongoing NAND production dynamics). This unusual situation makes external SSDs worth considering for certain applications. Practically any recent SSD in a 10 Gbps or faster NVMe enclosure will actually outperform internal SATA drives, which are limited by the 6 Gbps interface.
8TB SSDs: Largest Consumer SSDs Available
While significantly larger capacities exist in the enterprise market, eight terabyte consumer SSDs remain relatively rare (they were prohibitively expensive even before the NAND shortage), A notable change in 2025, however, was Samsung and SanDisk launching flagship Gen5 drives in 8TB options.

The most affordable 8TB SSD by a wide margin is the Samsung 870 QVO. Unsurprisingly, there’s also a wide performance margin between this SATA drive and any PCIe NVMe SSD.
The Samsung 9100 PRO 8TB is something of a milestone as it’s one of the first true flagship consumer Gen5 SSDs to reach this capacity. Using Samsung’s proprietary Presto controller and 8th-generation V-NAND, it delivers exceptional performance while maintaining reasonable thermals. The 8TB model includes 8GB of LPDDR4X DRAM cache and ships with an impressive 4,800 TBW endurance rating. At $999 for the base model ($1,019 with heatsink), it’s expensive but offers unparalleled capacity for a consumer Gen5 drive.
SanDisk has also announced an 8TB version of the WD Black SN8100, which should arrive in 2026. This drive will likely compete directly with Samsung’s offering, potentially with slightly better power efficiency as well as performance given the SN8100’s track record in smaller capacities.
Other 8TB M.2 NVMe/PCIe Models
1. Corsair MP600 Pro XT
One of the very few high-end M.2 drives that come in an 8TB version is the Corsair MP600 Pro XT. This flagship SSD from Corsair uses premium 176-layer NAND memory chips and the Phison E18 controller, resulting in sequential read/write performance of 7,100 MB/s and 6,800 MB/s, respectively. Random performance in the 4TB and 8TB capacities is also very impressive at 1M/1.2M read/write IOPS. The endurance rating is 6,000 TBW. Additionally, it comes bundled with a large aluminum heat spreader that is not optional but can be removed if it doesn’t fit in your build.
2. Corsair MP600 Pro NH
Corsair is more active than other manufacturers in the high-capacity space, with several drives on the market with confusingly similar designations. The MP600 Pro NH has a lot in common with the MP600 Pro XT, however, as they both use the Phison E18 controller and TLC NAND. There are also a few differences, most notably that the NH comes with no heat spreader and a more modest price tag. Sequential performance is also slightly behind at 7,000 MB/s (read) and 6,800 MB/s, but you get the same massive 6,000 TBW endurance rating with the 8TB model.
3. Mushkin Gamma
The 8TB Mushkin Gamma is yet another high-end Gen4 M.2 SSD powered by the Phison E18 controller but is specified as being slightly slower than the Corsair models (likely due to previous-gen NAND). It still gets quite close to the bandwidth limits of the PCIe 4.0 interface with a sequential performance of 7,000 MB/s (read) and 5,900 MB/s (write). Random performance is 700K/1M IOPS (read/write).
4. Sabrent Rocket Q 8TB
We have previously reviewed the 1TB model of the Rocket Q and found it to be an attractive M.2 drive from a price/performance perspective. As its name implies, the Sabrent Rocket Q uses QLC memory chips to keep costs down, but it still offers more than decent sequential performance at 3,300 MB/s (read) and 2,900 MB/s (write). The endurance rating for the 8TB capacity is 1,800 TBW.
External/Portable 4TB SSDs
If you just want lots of really fast storage to go, you actually have quite a few options. Unlike hard drives, solid state drives are not limited by the size of spinning platters, only by how the manufacturers decide to arrange the memory chips and layout of the PCB. Therefore they may vary greatly in size and shape.
What to keep in mind when shopping for an external SSD include the drive’s rated performance and its interface. The best-performing drives use either the USB 3.2 Gen 2 or Thunderbolt interfaces. Here are some of the most popular models right now:
Samsung Portable SSD P9 (USB4) – Announced at CES 2026, Samsung’s P9 is the world’s first 8TB external SSD with USB4 support, delivering up to 4,000 MB/s transfer speeds. Samsung claims the P9 improves read power efficiency by 333% and write efficiency by 405% compared to previous generations.
Samsung T7 Shield (USB 3.2 Gen 2) – Samsung’s T7 Shield comes in a rugged aluminum enclosure and offers transfer rates of up to 1050 MB/s via a 10 Gbps USB interface. It’s also highly portable with a thickness of just 0.5 inches.
Corsair EX100U (USB 3.2 Gen 2×2) – Using the 20 Gbps USB 3.2 2×2 interface, the Corsair EX100U can reach sequential transfer rates of up to 1600 MB/s (read) and 1500 MB/s (write), respectively. At 0.43 inches, it’s nevertheless even thinner than the Samsung T7.
WD My Passport SSD (USB 3.2 Gen 2) – Western Digital’s portable SSDs come in more conventional, HDD-inspired enclosures. The difference is that they are significantly smaller and, of course, much faster. In the latest incarnation, the My Passport SSDs use the 3.2 Gen 2 USB interface and offer read speeds of up to 1050 MB/s.
Build Your Own External SSD
When shopping for external storage, it’s also worth comparing the cost of a DIY alternative. Buying an affordable 4TB M.2 SSD and installing it in an M.2 PCIe/NVMe enclosure will often result in decent savings compared to branded external SSDs.
You also get to choose your own interface. Most external SSDs are limited to 10 Gbps USB 3.2 Gen 2, which is below spec for nearly all NVMe SSDs. Enclosures are also mostly 10 Gbps, but you are also free to opt for 20 Gbps USB 3.2 Gen 2×2 all the way up to 40 Gbps USB4/Thunderbolt.
NAND Memory Types and Endurance Ratings
As you may have noticed from the specs, the main differentiator in SATA SSD price brackets isn’t performance but endurance measured in terabytes written (TBW). For most of users, this isn’t a concern since none of the drives listed are likely to wear out before other PC components become obsolete.
What mainly affects endurance is the type of NAND memory chips used. These are exemplified in Samsung’s 2.5″ lineup by the 860 QVO (quad-level cell or QLC NAND), the 860 EVO (triple-level cell or TLC NAND), and the increasingly rare drives that still use multi-level cell (MLC) NAND.
MLC memory is the oldest NAND generation but still the superior technology in terms of performance and endurance. MLC has been mostly replaced by newer, denser TLC, which is somewhat slower and less durable. The most modern and least durable type today is QLC.
Additional bits in every cell increase the number of charge states in each transistor. This makes them more prone to voltage drift and other issues that need correction, which explains why high-density NAND doesn’t perform as well.
Of course, newer memory types aren’t without advantages. The main one is that higher densities allow for lower production costs. As for performance, the difference is quite small as long as you’re on the bandwidth-limited SATA bus. Compared to other technologies, modern QLC SATA drives offer an attractive price/performance calculation unless you plan on extremely heavy use.
Summary
If money is no object, or you happen to run a data center, it’s possible to buy SSDs in much greater capacities than 8TB, such as Samsung’s 30.72 TB PM1643. Enterprise drives are only limited by what businesses are willing to pay – which is typically a lot more than the average consumer. Prohibitive prices are what hold back ultra-high-capacity SSDs in the consumer space today.
The good news is that SSD technology continues advancing, with higher capacities becoming available each year. The concerning news in 2026 is that the NAND shortage is having a very noticeable effect on pricing. What was once a steady march toward cheaper storage is currently the opposite. A 1Tb TLC chip that cost $4.80 in July 2025 was $10.70 in December. Prices are expected to continue rising through 2026 and potentially into 2027.
PC builders on a budget may have to return to combining a lower-capacity SSD with a traditional hard drive for backups and infrequently accessed files. However, certain categories of users benefit significantly from large amounts of fast storage space. Photo, video, and audio editing professionals come to mind, as do gamers with extensive libraries of modern titles that now routinely exceed 100 GB per game.
The options are more plentiful than ever before, but purchasing decisions have become more critical. With all 2026 NAND production capacity already sold out and new fabrication capacity not coming online until late 2027, waiting for lower prices is a long-term strategy. If you really need high-capacity storage, it is probably better to buy sooner rather than later in 2026.
You forgot the OWC Express 4M2 NVMe, which offers true Thunderbolt 3 performance. You can bolt in four Sabrent 1TB Rocket NVMe PCIe M.2 SSDs and get a 4TB external drive with 2,883 MB/s read speeds for about $900. ?
