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. 4TB SSDs are now quite common, but we are also starting to see 8TB models in the consumer market.
From a manufacturer’s perspective, building SSDs in capacities up to 8TB and beyond is more of a pricing issue than an engineering challenge. Although common in data centers, the largest SSDs are simply too expensive for mass market adoption. Nevertheless, the cost of Flash memory has been dropping for some time. And thanks to the arrival of cheaper chips in the form of high-density TLC (triple-level cell) and QLC (quad-level cell) NAND, it is now easier than before to justify investing in large drives.
Here, we’ve rounded up the best 4TB and 8TB SSDs from major manufacturers as of early 2023. The number of alternatives has grown significantly in the past year and there are now quite a few high-capacity drives available in all common form factors.

Fastest Vs. Best Value 4TB Gen4 M.2 SSDs
Cost per GB is always a key factor when buying a storage device, and it is of course particularly important when shopping for a high-capacity SSD. Other than performance, it is mainly the type of Flash memory used that determines the price tag. Newer drives based on QLC (quad-level cell) memory tend to be cheaper, but also slower and offer less endurance than high-end SSDs based on TLC (triple-level cell) chips.
This quickly becomes apparent when comparing some of the fastest 4TB SSDs versus the most affordable.

The WD Black SN850X is currently one of the fastest M.2 SSDs overall and does particularly well in benchmarks that mimic real-world usage, like 3DMark Storage and PCMark 10. It’s also backed by a solid 2,400 TBW endurance rating, meaning that it should withstand 600 full drive write/erase cycles before wearing out.
At the affordable end of the spectrum – but still utilizing the fast PCIe 4.0 interface – we find the Crucial P3 Plus. This drive uses cheaper QLC NAND of the modern 176-layer variety but still offers an attractive mix of performance and value. Although its endurance rating is lower compared to the high-end alternatives, the P3 Plus ships with the same industry-standard 5-year warranty, which is not always the case in the entry-level space.
List of 4TB M.2 (PCIe/NVMe) SSDs
PCI Express-based solid state drives in the M.2 form factor are the first choice as system drives, as they offer much higher performance than their 2.5″ SATA counterparts. However, some of the most popular high-end drives such as the Samsung 980 PRO are not available in 4 TB capacities. Many of the 4TB or larger alternatives are technically entry-level M.2 SSDs and frequently use more inexpensive parts, e.g. QLC NAND. Here is an extended list of current 4TB M.2 PCIe SSDs at the time of writing, roughly sorted by performance.

Note that all drives with sequential speeds above 3,500 MB/s require a PCI-Express 4.0 (PCIe Gen4) platform to reach their full potential. The PCIe Gen4 interface is present in consumer platforms based on:
- AMD X570, B550, or TRX40 motherboards paired with a 3000/5000-series Ryzen/Threadripper CPU (or later)
- Intel Z590 and other 11th-gen motherboards paired with an Intel Core CPU from the same generation (or later).
Some highlights from the list (other than those mentioned above):
1. High-End 4TB M.2/NVMe SSD: Kingston KC3000
Launched in 2022, the Kingston KC3000 is among the fastest 4TB M.2 SSD at the time of writing. It is based on the Phison E18 controller and ultra-fast 176-layer Micron TLC NAND. These are the same parts as found in the Seagate FireCuda 530 (see below), but Kingston’s model seems to offer slightly better performance than the average E18 drive. Note that this drive is also available in a slightly faster version sold under the name Fury Renegade.
Check availability: Amazon, Newegg, Amazon UK
2. Superb Endurance & Performance: Seagate FireCuda 530
Seagate’s FireCuda 530 uses the same controller as the KC3000 and offers stellar sequential read/write performance at 7,300 MB/s and 6,900 MB/s, respectively. The 4TB model also comes with an exceptional endurance rating of 5,100 TBW, making it a top choice for video editing and other storage-heavy workloads.
Check availability: Amazon, Newegg, Amazon UK
3. Great Gen4 Performance for Less: Sabrent Rocket 4 Plus
Sabrent’s Rocket 4 Plus was one of the performance leaders in the M.2 space last year but now often sells for less than the leaders mentioned above. It still performs very well in a Gen4-capable system, offering sequential read speeds in excess of 7,000 MB/s and write speeds that are not far behind.

List of 4TB 2.5″ SATA SSDs
If you are looking for lots of fast internal storage space at a more reasonable cost, SATA drives should (and usually do) offer lower prices per GB compared to their M.2 PCIe counterparts. For quite some time Samsung was the only manufacturer with 4TB or larger consumer SSDs in the market. More recently, Western Digital/SanDisk and Seagate have also started to offer high-capacity alternatives.
These are the leading 4TB 2.5″ SATA SSDs available at the time of writing.

Sequential performance is fairly similar across the board, which is not surprising considering that the SATA interface has been fully utilized by leading SSDs for many years. However, the 2.5″ form factor is still interesting as it offers higher capacities at (usually) much more attractive prices per GB. It is, of course, also the only alternative if you have no spare M.2 slots. Some of the highlights worth mentioning include:
1. Still a Market Leader: Samsung 860 PRO
The 860 PRO is quite possibly the last drive from Samsung to use high-quality MLC NAND. Like previous Samsung PRO-series SSDs, it has a rock-solid reputation for reliability, endurance, and not least performance. It has been around for several years now but is still one of – if not the – best SATA SSD you can get your hands on. Unfortunately, its MLC chips also make this drive significantly more expensive than most of the competition, which is particularly noticeable in the largest 4TB capacity.

2. Great Performance & Value: Seagate Firecuda 120
For most users, a high-end, MLC-based SATA SSD like the Samsung 860 PRO does not represent value for money at this time – not least because spending that much will get you a significantly faster PCIe/NVMe M.2 SSD. If you nevertheless want a high-end model, a better case can be made for the Seagate FireCuda 120. This relatively recent drive, launched in 2020, now tops the performance charts in key areas, while also offering an exceptional endurance rating at 5,600 TBW for the 4TB capacity.

3. Affordable & Reliable: WD Blue 3D NAND
You may have noticed that the WD Blue 3D and SanDisk Ultra 3D specifications are identical. This is because these two drives indeed are identical in all but name and branding (SanDisk is a subsidiary of Western Digital). However, the WD Blue 3D NAND tends to be slightly cheaper for some reason, thus making the choice between the two a no-brainer. Although its endurance rating is relatively poor compared to other 4TB SSDs, the WD Blue has one of the best overall user ratings in the segment. At the same time, real-world performance is comparable to much more expensive alternatives.

8TB SSDs: Largest SSDs in the Market
While significantly larger capacities are available in the enterprise market, eight-terabyte consumer SSDs appeared only recently and are still not numerous. Most use QLC NAND memory to keep prices at a reasonable level and there are very few options in the high-end segment other than the Rocket 4 Plus.
Last update on 2023-03-20 / Affiliate links / Images from Amazon Product Advertising API
The most affordable 8TB SSD by a wide margin is the Samsung 870 QVO. Unsurprisingly, there is also a rather wide performance margin between this SATA drive and any PCIe NVMe SSD. One of the more recent additions to the M.2 SSD market is the Sabrent Rocket 4 Plus 8TB, which is also the best-performing 8TB drive at present.
As mentioned, the list of 8TB consumer SSDs is not particularly long at this point in time, and availability is often limited.
One SATA Alternative: Teamgroup QX
At the time of writing, there is only one non-enterprise competitor to the 8TB Samsung 870 QVO and the Teamgroup QX is it. In fact, this drive is also available in an even more capacious (and expensive) 15.3TB variety. Like the 870 QVO, the QX is based on QLC NAND and should offer about the same performance. They are also priced about the same, though the Teamgroup QX comes with an inferior endurance rating at 2,000 TBW versus the QVO’s 2,880 TBW.

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. 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.
Check prices: Amazon, Newegg, Amazon UK
3. Corsair MP400 8TB
Corsair’s MP400 is another recent release based on high-density QLC NAND. Its specifications are quite similar to the Sabrent competitor at 3,480 MB/s sequential read and 3,000 MB/s sequential write transfer rates. The same goes for the endurance rating, which is 1,600 TBW for the 8TB model. Considering the large capacity, these ratings are actually fairly low. This is however compensated to an extent by the sheer amount of storage space. Unless you shuffle lots of data around on a regular basis, any 8TB SSD is highly unlikely to wear out before the warranty expires.

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 on 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 Gen2 or Thunderbolt interfaces. Here are some of the most popular models right now.

There are also a few other high-capacity alternatives on the external SSD market:
Oyen Digital U32 Shadow Dura – This is, unsurprisingly, a close relative to the previously mentioned U32 Shadow from Oyen Digital. The difference is that it comes in a more durable rubber-enclosed case, making it shockproof and somewhat water-resistant. At least according to the manufacturer (we could find no IP-rating though). Check price >>
iStorage diskAshur PRO2 – If you value security higher than any other aspect, then – and only then – this might be the drive for you. It comes with a code lock and all the military-grade security certifications you can imagine. You also get AES-XTS 256-bit hardware encryption. Check price >>
BUSlink Disk-On-The-Go External Slim Portable – BUSlink offers external SSDs in sizes all the way up to 7.68 GB. In other words, they likely use enterprise SSDs from Samsung or Micron inside. The drive uses the USB 3.1 Gen2 interface, offering up to 10 Gbps of bandwidth. Unfortunately, BUSlink doesn’t provide any more detailed performance data. Check price >>
OWC Express 4M2 NVMe – OWC’s 4M2 is a configurable cabinet with the capacity to house up to 16TB of ultra-fast SSD storage space using four internal slots. Thanks to its Thunderbolt 3 interface, it reaches transfer rates of up to 2800MB/s. Interestingly, it’s also equipped with a DisplayPort output. Check price >>
Memory Types and Endurance Ratings
As you may have noticed from the specs, the main differentiator in the different 2.5″ SATA price brackets is not so much performance as it is endurance measured in terabytes written (TBW). For the vast majority of users, this is not a major concern, since none of the drives listed above are likely to wear out before all other parts of the computer have turned to scrap.
More recent NAND allows for storing additional bits per cell, with the drawbacks of reduced endurance and performance.
What mainly affects the endurance rating is the type of NAND memory chips use. These are exemplified in Samsung’s 2.5″ lineup by:
- the 860 QVO, which uses quad-level cell (QLC) NAND chips
- the 860 EVO uses triple-level cell (TLC) NAND, and finally
- the 860 PRO, which is one of the increasingly rare SSDs 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 the newer and denser TLC type, 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 to be corrected, which is a reason why high-density NAND doesn’t perform as well.
Of course, the newer memory types are not without advantages. The main one is that the higher densities allow for lower production costs. And as for performance, the difference is quite small as long as you are on the bandwidth-limited SATA bus. Compared to other technologies, modern QLC SATA drives offer an attractive price/performance calculation, unless you plan on putting the drive through 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.
Evolution of NAND Flash memory.
The good news is that SSD prices have dropped at a steady pace, partly thanks to smaller production processes (in nanometers), but mostly thanks to additional bits per cell. However, the cost per GB is obviously still high compared to mechanical hard drives. For most PC builders today, the most cost-effective solution is still to combine a lower-capacity SSD with a slow conventional hard drive for backups and other files that are not frequently accessed.
On the other hand, some categories of users can definitely take advantage of large amounts of fast storage space, which is an advantage for everyone working with large files. Photo-, video- and audio editing come to mind.
The options are still somewhat limited, but it is 100% certain that we’ll see more high-capacity SSDs in the future. And hopefully at reasonable prices, thanks to the proliferation of QLC NAND and more efficient production processes.
