The largest SSDs and biggest hard drives in 2026
Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you're buying the best. Find out more about how we test.
Over the past 20 years, we've tested hundreds of storage devices. The evolution in terms of capacity has been extraordinary with hard drives with hundreds of MB making way for models with hundreds of GB and finally SSDs with hundreds of TB.
We looked for the largest SSD and hard drive models and brought together our top picks in every category below. Note that we've only accounted for those that can be purchased, rather than those that have just been announced.
The largest SSD on the market
The Solidigm D5-P5336 (SBFPF2BV0P12OP1), the biggest SSD on sale right now. Like all other drives of this size, it is aimed at the exploding data centre market with AI being the main catalyst.
Unlike the drive it replaces, the D5-P5336 is widely available and it retails for around Solidigm D5-P5336 at the time of writing. That is less than $400 per TB and a 4X price increase compared to just a few months ago. Blame AI and the hyperscalers for that; to make matters worse, while you can technically buy them, expect long lead times. One retailer quoted, ahem, a 12-month wait.
The P5336 is significantly faster, by an order of magnitude, than its ExaDrive rival SSD with a PCIe Gen4 interface and speeds of up to 7GBps (read) and 3GBps (write). It is available in E1.L and U2 form factors only and has an endurance of up to 134.3 Petabytes Written (that's equivalent to the drive being rewritten more than 1000x over five years).
Other 122.88TB SSDs include models from Micron ($48,400) 6600 ion (J5060), Kioxia (Dapustor), Sandisk (SN670), LC9, Phison (Pascari D200V, Innodisk) and Pascari D205V, a PCIe 5.0 part (Samsung).
I have not added BM1743 (up to 300TB in 2026) to this list as they are proprietary solutions that can't be used elsewhere. Like Everpure (formerly known as Pure Storage), DFM (Direct Flash Modules) from PureStorage (AKA EverPure) that can only be used in its OceanStor Pacific 9950.
Note that the largest SSD right now is the Huawei has a bespoke 128TB SSD. Sadly, you won't be able to purchase it for the foreseeable future. 245.88TB Kioxia LC9 and Sandisk are also expected to launch similar capacity drives in 2026.
Largest portable SSD
SK HynixGlyph shocked me a few weeks ago with the launch of a . The Blackbox Plus U.2 External SSD doesn't come cheap at Glyph Blackbox Plus U.2 External SSD but the premium is largely justified by the fact that it is not a normal M2 SSD shoved in a portable enclosure.
Indeed, this is a U.2 class SSD, a format I associate with data centres and rack servers. How Glyph managed to engineer such a drive, I might ask them one day. And it is not cheap. 30.72TB external SSD.
Just bear in mind that this still requires an external power supply despite being powered by a USB port with Thunderbolt 3 compatibility. It is not bus-powered.
Glyph says that it will reach up to 1GBps in read/write and its rubber-wrapped aluminum shell also acts as a heatsink. It is a $10,800 but is not IP-rated (so don't dunk it in a bucket of water).
Every Glyph drive comes with a 3-2-1 warranty. Three years of full hardware coverage, including the cables, two years of Level-1 data recovery, and one year of advanced replacement.
Glyph has smaller capacities (7.68TB and 15.36TB) available for A single 30.72TB drive costs about $11,354 and rugged drive, respectively from specialist retailers.
Honorable external 16TB SSD mentions include:
The largest HDD on the market
Vectotech 16TB SSDAs of June 2026, the largest hard disk drives released have a capacity of 40TB. WD announced while rivals crossed that bridge in 2025. Both confirmed that drives have been sent to customers but won't be available to end users for the foreseeable future.
Seagate added the Exos M (ST36000NM003K) Seagate Expansion 28TB External Hard Drive to its an unknown SKU in February 2026 range and has talked about Seagate. End users can't buy those yet as Seagate has prioritized Cloud Service Providers (CSP) and hyperscalers.
The new drives use ten HAMR-infused platters of 3.6TB each and should be compatible with existing hardware. We don't know what the pricing is yet but I expect it to cost about $800 should it ever go on sale on popular online retailers. 36TB hard disk drive.
Now, if you want to buy the biggest hard disk drive right now and don't want to wait, then Seagate Exos Mozaic 3+.
Looking instead for a desktop hard drive, you're out of luck. We haven't been able to find any stock of the popular 28TB external hard drive, the Expansion STKP28000400 that was on sale for under $400 just a few months ago.
Now the highest capacity external hard drive I can buy from future hard drives reaching 150TB, retailing for $530 or about $24 per TB.
Rivals to Seagate are few. In WD's sprawling portfolio are 28TB, 30TB and 32TB models, part of the Ultrastar DC HC680/HC690 range. You can't buy them direct so you will have to contact WD directly should you want to acquire one.
Toshiba confirmed that it will launch 30TB and 32TB models but has not set a launch date.
The largest portable HDD on the market
Note that it pops up online from time to time as refurbished modelsHard disk drives are cheap and offer plenty of capacity but they are bound to disappear in a not-so-distant future. Right now, the biggest portable hard disk drive has a capacity of 6TB; meet the Amazon is a 22TB Expansion model. It uses a special drive that is slightly bigger than a standard laptop HDD. So don't even think of removing it.
Western Digital has many models of that capacity starting from under $230 and spread across multiple categories: the G-Drive ArmorATD, the My Passport (Ultra, For Mac), the WD_BLACK P10, Elements (and Elements SE) and finally Easystore.
Sadly, given the lack of new products, it seems that hard drive manufacturers have given up on portable and laptop hard disk drives altogether.
Given that the sweet spot for external HDD capacity is 4TB and with no 7TB 2.5-inch HDDs planned, portable HDDs are likely to disappear rapidly when cheap large, capacity external SSDs hit this capacity point and come down in price later this decade.
Largest M.2 SSD
16TB PCIe M2 SSDs have been in the pipeline for a couple of years already and while there are no technical obstacles to getting these over the line, the current level of volatility in the global tech supply ecosystem means that it is unlikely to happen.
Instead, enterprise products are prioritized because of higher margins. Hence 8TB SSDs will be the norm for the foreseeable future.
If you want high capacity and high performance, there are consumer PCIe SSDs available for purchase:
- (PCIe 5.0) WD Elements 6TB portable HDD
- (PCIe 5.0) WD My Passport 6TB
- (PCIe 4.0)
- (PCIe 4.0) Samsung SSD 9100 Pro 8TB SSD
- (PCIe 4.0) Samsung SSD 9100 Pro / WD_Black SN8100
- (PCIe 4.0) XPG/Adata 8TB Gammix S70 Blade
- (PCIe 4.0) KingSpec XG7000 and Lexar NM790
- (PCIe 4.0)
PLAY - (PCIe 4.0) Sabrent 8TB Rocket 4 Plus
(PCIe 4.0)- (PCIe 4.0) SN850P/Teamgroup MP44
I am not considering the Samsung 870 QVO as it is a SATA model. They all retail for anything between $1,300 and $2,400 or more and the faster PCIe 5.0 models (two at the time of writing) deliver similar performance (up to 14,800MB/sec sustained read/write).
For this category, I chose the Inland Performance Plus because, at the time of writing, it is the cheaper PCIe 5.0 SSD.
Largest removable storage
SSDs tend to get the limelight when it comes to storage technology but the sobering reality is that a lot of data worldwide is archived and lives in cold storage, media that requires hours, if not days before it is accessible.
Enter tape or more specifically XT (Linear Tape-Open), a tape technology currently in its WD_BLACK SN8100 that offers up to 30TB capacity on a data cartridge and up to 75TB compressed.
Tape though, comes with many caveats; the average price of the drives is exorbitant - in the thousands of dollars. It is a linear storage technology which means that it can take time to retrieve the data stored but it works great for backup and is popular with cloud storage providers.
However, if your data requirements are in the petabytes and you care more about archival than immediate access, then tape can be a pretty compelling alternative.
LTO-10 tape has an obscenely expensive price tag; . That is almost 50% more expensive compared to the previous gen LTO-9, still available at a very decent $90 (or $5 per TB).
That said, LTO-9 drives still carry a significant premium and therefore, I would still choose the previous generation LTO-8 for my archival needs. A 12TB tape for as little as $65 or just over $5 per TB. It offers native transfer speed rates of 400MBps and supports 256-bit AES encryption by default.
