4TB SSDsIf 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 and we are also starting to see 8TB models in the consumer market.

From the manufacturers’ perspective, building SSDs in 8TB or even larger capacities is a pricing issue rather than an engineering challenge. Although common in data centers, really large SSDs are simply too expensive for the mass market.

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 solid state 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 & 8TB M.2 SSDs

Cost per GB is always a key factor when buying a storage device, and it is of course especially 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. On the downside, they are also slower and come with much lower endurance ratings than high-end SSDs based on TLC (triple-level cell) chips.

This quickly becomes apparent when comparing some of the fastest 4 TB SSDs versus the most affordable.

Crucial T700If you have invested in a PCI-Express 5.0-capable system (based on e.g. AMD B650/X670 or select Intel Z790 boards), the best-performing 4TB SSD is currently the Crucial T700. With sequential throughput of up to 12,400 MB/s, this drive is a leader among the still relatively few SSDs that utilize the Gen5 interface. For the same reason, it is also the fastest M.2 SSD overall.

The WD Black SN850X is one of the best SSDs in the Gen4 space and does particularly well in benchmarks that simulate real-world scenarios, 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. Read our review of the 4TB model here.

At the affordable end of the spectrum – but still using the fast PCIe 4.0 interface – we find SSDs like 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 an industry-standard 5-year warranty, which is not always the case in the entry-level space.

If you are looking for 8 TB of fast storage space at a somewhat reasonable price, the Corsair MP600 PRO NH is one of the most interesting new releases. It’s based on the Phison E18 controller and durable TLC NAND, resulting in an outstanding 6,000 TBW endurance rating.

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 and 990 PRO are currently 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, such as budget controllers and QLC NAND. Here is an extended list of current 4TB M.2 PCIe SSDs at the time of writing. It is roughly sorted by random IOPS throughput, which tends to be the more accurate indicator of real-world performance.

*Prices are updated automatically at regular intervals but are subject to change between updates.
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

kingston kc3000Launched 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.

2. Superb Endurance & Performance: Seagate FireCuda 530

Seagate Firecuda 530Seagate’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.

Adata XPG Gammix S703. Great Gen4 Performance for Less: XPG Gammix S70 Blade

Adata’s XPG Gammix S70 Blade stands out in the crowd by using the somewhat unusual IG5236 “Rainier” controller from Innogrit. Although its random IOPS performance cannot compete with the class-leading Gen4 SSDs, sequential performance is very impressive at 7,400 MB/s (read) and 6,600 MB/s.
It is also highly competitive in terms of pricing and the 4TB model offers a solid endurance rating of 2,960 TBW. Additionally, it ships with a heatsink suitable for the PS5.

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:

Samsung 860 PRO1. 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.

Shopping links: Amazon, Newegg, Amazon UK

Seagate Firecuda 1202. Great Performance: 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. It has unfortunately become difficult to find.

Shopping links: N/A

WD Blue SATA3. 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.

Shopping links: Amazon, Newegg, Amazon UK

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.

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.

teamgroup qxOne 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
Corsair MP600 Pro XT1. 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.

corsair mp600 pro nh2. 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.

Mushkin Gamma3. 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).

Sabrent Rocket Q 4TB NVMe SSD4. 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.

The Best 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.

Note that high-end external SSDs that use Thunderbolt require compatibility with the interface. This is a standard feature on recent Macs, but not on PCs, where it is mainly found on creator-oriented motherboards. USB 3.2 Gen 2 (10 Gbps) and USB 3.2 Gen 2×2 (20 Gbps) ports are far more common but only on more modern PCs. Unlike Thunderbolt, however, high-end USB devices are backward-compatible but will run slower on old hardware.

There are of course additional high-capacity alternatives on the external SSD market. Some of the most popular include:

Samsung T7 Shield 4TB SSDSamsung 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. Amazon link >>

Corsair EX100UCorsair 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. Amazon link >>

WD My Passport SSDWD 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. Amazon link >>

Build Your Own External SSD

Installing an SSD in the Orico 20 Gbps enclosureWhen 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 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.

Comparison of different NAND memory types

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.

NAND memory

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.

  1. VectoTech Rapid take apart disassemble would be great to see internal SSD. Is it Micron?

    On the other hand, your information is outdated:
    VectoTech Rapid 2TB External SSD USB-C Portable Solid State Drive (USB 3.1 Gen 2)
    https://www.amazon.com/VectoTech-Rapid-External-Portable-Solid/dp/B01JKMZ6L6

    Check out the pictures with USB C connector and cables. Albeit the speed is outdated. Amazing!

    • Thanks for the info, will uppdate asap. I have yet to see a full review of the vectotech. But Micron or Toshiba NAND would be the most likely.

  2. More with updated speed information:

    VectoTech Rapid 4TB External SSD USB-C Portable Solid State Drive (USB 3.1 Gen 2)
    Super fast Read/Write speeds up to 540Mb/s
    https://www.amazon.com/dp/B01NC1RI61

  3. Thanks. Please, note that the article text still states:
    “The VectoTech Rapid is bound by the limits of the USB 3.0 (or USB 3.1 Gen1) interface and it’s, therefore, slower than its competitors”.

    On the other hand:
    Brand new higher-capacity internal SSD (4 TB & 8 TB) from Micron will allow higher-capacity external portable SSD
    https://forums.macrumors.com/threads/brand-new-higher-capacity-internal-ssd-4-tb-8-tb-from-micron-will-allow-higher-capacity-external-portable-ssd.2208536

  4. 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. ?
