It’s crazy to think how far we’ve come since the days of marveling at 20MB drives & even smaller portable storage.

Who knew 30 years later, we’d be enjoying 1TB flash drives, 1TB microSDs &, of course, 8TB solid-state drives!

There are now some very decent 8TB offerings available from leading storage manufacturers, but they still vary heavily in type, quality & price.

So today’s feature is here to guide you through the best 8TB solid-state drives, with different budgets and requirements in mind.

Top Picks

Quick word on where to buy 8TB SSDs

If you’ve already looked at 8TB SSDs online, you may have run into some products that are 80-90% cheaper than the reputable options we recommend below.

How is that possible?

As you may have guessed, I’m here to tell you these cheap listings are fake 8TB SSDs, usually made using a smaller drive with data re-writes to make them “appear” like they are 8 terabytes (but will quickly stop working when pushed above their original spec).

You have to be very wary of such listings, they often still come with a host of good reviews by using an old product page (e.g. a well-rated 1TB SSD) and then updating it to an 8TB fake.

We’d recommend sticking to the options on this list that represent the best value for authentic 8 TB solid states, and even when buying our recommendations, remember to purchase from Amazon directly (or one of their third parties with excellent customer feedback).

If you still want to look at other options, we strongly suggest sticking to reputable brands like Samsung & Corsair.

Best 2.5″ 8TB SSD: SAMSUNG 870 QVO

What a fantastic offering this is.

From one of the kings of flash memory, Samsung’s 870 QVO product line doesn’t just offer enormous size options but does so with great technology to ensure decent longevity while still managing to be the cheapest 2.5-inch 8TB SSD we’ve come across.

Not only does the 870 QVO boast read speeds up to 560 MB/s & write speeds up to 530 MB/s, but benchmarks also suggest that speeds get close to these numbers in real-world performance (this isn’t always the case, with “maximums” provided by manufacturers occasionally not mirroring reality).

Having excellent speeds is integral for many people with larger drives when considering the significant data transfer that can take place between your various storage units.

The specs also make the 870 QVO a fantastic 8TB SSD for PC gaming (if you’re buying for a console like the PS5/Xbox Series X, be sure 8TB is supported – if not, the 2/4TB versions are also well worth their smaller price-tags).

Based on QLC technology to achieve its excellent price-point, Samsung works around the usual limitations of a QLC SSD setup by implementing an Intelligent TurboWrite & a stability-focused ECC algorithm to ensure terabytes written (TBW) up to 2800 (twice that of the previous iteration, which was already a well-received, stable product by QLC standards).

Whether you’re after an 8TB SSD for video editing, general storage, or other average user needs, we really appreciate the longevity on offer here (if your requirements are for your OS running as fast as possible, the 870 QVO is still a decent choice, but you may want to consider the M.2 picks below).

While it’s nothing to go crazy for, we appreciate the decent design and build quality of the 870 QVO too; balancing minimalism and sturdiness in its tiny package.

Another nice-to-have is software capability; the utility for data migration/cloning, Samsung Magician speed optimization, and general drive management are fantastic additions and all easily available.

Finally, it’s worth noting the incredible value of the 870 QVO. It has little diminishing returns price-wise, with the 8TB SATA SSD version (usually) costing around double a 4TB SSD. This is a great feat, with larger drives often coming with a premium for their utility in only taking a single output.

Ticking practically all the boxes we think most users are looking for in a serious storage solution for their computers while maintaining a fantastic price, the 870 QVO is easily our overall top pick for the best 8TB solid-state drive today.

2022 Update: The 870 QVO is still our number #1 pick for the best 8TB SSD on the market in 2022, nothing else in the market has yet come close.

Best M.2 8TB SSD: Corsair MP400

If you’re after the fastest 8TB solid-state drive possible for a PC setup, power-house brand Corsair has a brilliant offering for M.2 NVMe users.

With read speeds up to 3400 MB/s & write speeds up to 3000 MB/s, we’re pleased to say that, like the Samsung 870 QVO, the benchmarks and user reception demonstrate that these speeds are attainable in real-world performance.

Not only is this the fastest 8TB SSD worth buying in today’s market, but its 3d QLC NAND architecture still boasts up to 1,600 TBW, a great balance between longevity and the cheaper utility of QLC.

The great differentiation between the MP400 and the 870 QVC (other than port requirements) is the price.

As fast as the MP400 is, it comes at over 50% more expensive than the 870 QVC.

Would we recommend it as one of the best SSDs for your operating system and intensive read/write requirements? Absolutely.

But appreciating the high cost, it’s worth point out that while the MP400 is 6x faster than nearly all of its 8TB SATA SSD competitors, that does not translate to anything close to 6x operational performance (e.g. 

In other words, while it’s a great investment if you can afford it, running your system from the 870 QVO would still provide decent speeds (you could also combine it with a smaller MP400 M.2 drive running your OS/main software and an 870 QVO 8TB for your general storage/media if you want to optimize cost and speed).

If you’re running cloud storage, or an intensive virtual machine setup, investing in MP400s will be fantastic if you have a motherboard with decent M.2 capability.

Unlike traditional SATA solid-state drives, it’s a little more common to see larger NVMe 8TB SSDs cost more per byte for their additional size.

In other words, for the MP400 8TB, you can expect to pay around 5-10% more than 2 MP400 4TBs. But with M.2 slots usually more limited than SATA outputs, we think the extra price is more than worth it for users serious about maximizing their storage.

With unrivaled speeds, size, and great compatibility across PCIe, the MP400 may be expensive, but considering you’re getting one of the best M.2 drives in any category, we think it’s more than worth its hefty price tag.

Best External 8TB SSD: Glyph Atom Pro

While Glyph may not be a household name like Samsung and Corsair, they’re a reputable manufacturer, especially in the premium SSD space.

One of the best examples of their accomplishments is the Atom Pro, which doesn’t just provide a portable, rugged 8TB external SSD, but also one that operates on an NVMe interface to reach speeds comparable to some of the best M.2 drives.

With read speeds of up to 2800 MB/s and write speeds up to 2600 MB/s (that are actually attainable in real-world performance based on benchmarks and user hands-on), they may be a tad lower than our top M.2 above, but to achieve these speeds for an external solution that needs to also balance portability/durability? The Atom Pro’s specs are very impressive.

There are a few reasons we consider it better than the competition, but the main one is that we think the type of users after an 8TB external drive will more likely be those looking for significant transfer speeds and/or read speeds.

Whether you’re a 4k 60FPS video editor, production users, or someone who wants to use this enormous space for a dedicated portable PC storage with OS/Games/media, the NVMe specification and speed of the Atom Pro poses a lot of value to you.

Its capability as a powerful portable storage solution is really solidified by its build quality; not only is it deceptively small (with a nice crevice around the sides to fit the cable through during travel), but it’s one of the most durable SSDs we’ve come across, even boasting 810F military standard grading to endure intensive conditions.

With all that said, while we do rank this as the best external 8TB solid-state drive, we appreciate that it is a very expensive offering.

As stunning as the read/write speeds are on a portable solution, if you don’t see yourself using them to their full effect (e.g. running an OS from an external SSD or transferring large files with a focus on haste) then you may be better off looking at our cheaper external pick below.

It’s worth adding that you need a device that supports Thunderbolt 3/4 to achieve the specified speeds (formatted as a Mac SSD, but easily changed to a Windows drive with a simple reformat at the point of install). We would have liked to see an in-built USB-C.

That said, with an adapter, it would undoubtedly still reach decent speeds on another connection, but if you’d prefer a built-in solution (or don’t need to pay extra for the additional speed), our cheap external SSD choice below will better suit you.

We’re floored by what Glyph has put together with the Atom Pro; with unparalleled durability, portability, speed, and storage size.

If you have the budget, know that you’re not just getting one of the best 8TB external solid-state drives, but one of the great portable storage solutions in any category.

Cheapest External 8TB SSD: VectoTech Rapid

In the world of 8TB SSDs, cheap is a relative term.

While still expensive, the VectoTech Rapid offers fantastic value when compared to some of its closest competitors and will likely be the better answer for many external drive users who don’t need the immense NVMe speeds of our pick above.

Led by a 3d NAND setup, we appreciate the Rapid running on a USB 3.1 Gen 2 Type-C connector which, in our opinion, is the best input today with great balance between speed and compatibility.

With speeds up to 540MB/s (reflected largely in benchmarking), the Rapid may be slower than the Atom Pro, but at its price-point, it offers great value for less average users.

As nice as it is to use an NVMe setup for anyone who has demanding read/write needs, it’s worth point out that the capability of the VectoTech SSD is still great for those who prefer the cost savings over the change in spec.

With speeds akin to our top 2.5-inch SATA Samsung pick, the VectoTech is still perfectly capable of running an OS, 4K video editing (@30FPS), and other demanding activities.

Despite being a cheap external 8TB SSD (relatively!), we appreciate the decent demonstrations of longevity for the Rapid. Its smaller brothers were introduced on the market several years ago, with many long-term users citing a persistence of great performance.

When you tie that in with the 3-year warranty and durable aluminum frame, it’s nice to see no compromise made on ensuring the lifespan of the Rapid considering the investment.

Yes, it may not reach the heights of the Atom Pro, but for around half the price? It’s undoubtedly the best external 8TB drive with value in mind.

Runner-Up Best NVMe 8TB SSD: Sabrent Rocket Q

Of all of the head-to-heads that were considered here, nothing was as close as Corsair MP400 vs Sabrent Rocket Q 8TB.

Both from 2 power-house storage manufacturers boasting 5-year warranties as a testament to their longevity (with up to 1,800 TBW on the Rocket Q, it comfortably gets around the limitations of QLC compared to lesser SSDs).

Both 8000GB SSDs also sell for close-to-identical pricing, so the value isn’t a competitive difference either.

The main reason we rank MP400 as number #1 is purely down to its slightly superior speeds, up to 3400MB/s read & 3000MB/s write vs Sabrent’s 3300MB/s read & 2900/s write.

Benchmarks also suggest that the Rocket Q runs slightly hotter than the MP400, but not to the points of concern (i.e. a decent cooling solution/M.2 heatsink should be suitable for operation).

These are negligible differences, but with both SSDs representing excellent specs across the board, they’re the only real separators.

We would take this as a good thing, as it means anyone in the market has 2 fantastic options; if this Rocket Q offering is cheaper or available when the MP400 isn’t, then by all means go for it.

The Rocket Q is comfortably in the same league and very close to equally worthy of the best 8TB M.2 NVMe SSD title.

Best Enteprise 2.5″ 8TB SSD: Intel SSD DC P4510

If you are looking for a solution for serious business-grade storage (or simply want the highest-end 8TB SSD for general consumption) this Intel SSD is your best choice.

The P4510 series stands out by fitting the 2.5″ form factor while utilizing a U.2 PCIe connection to achieve 3200 MB/s read & 3000 MB/s write speeds (reflected in hands-on benchmarks).

Not only are the read/write speeds almost comparable to our top M.2 pick, but the P4510 series boasts excellent secondary specs that promote it as a great tool for business-level storage (virtual machines and other high-grade needs), with very low latency and fantastic read/write IOPS ratings.

Important note: To be clear as above; this drive does not operate on a SATA connection like a traditional 2.5″ SSD. You need a U.2 output on your motherboard (needed to reach the speeds that SATA cannot provide), so ensure your motherboard has this available before purchasing.

The other standout point where the P4510 earns its price tag is its TLC-based lithography.

Intel, who is one of the most reputable brands for enterprise-tier storage, manage to use this TLC setup to achieve a mean time between failure (MTBF) of 1.5 million hours.

The drive is also optimized compared to many higher-end SSDs for great temperature ranges and low vibration ratings (again, clearly a focus for critical enterprise server usage in mind with this level of quality).

There’s no denying that this longevity is a stunning offering and we know that some users will specifically be looking for an 8TB TLC drive, but the idea that QLC is always a big problem is a bit of an over-simplification.

Yes, drives use QLC architecture to meet mainstream prices, but stand-out choices like our top Samsung QVO pick dramatically increase the TBW to double that of the previous iteration/many competitors.

And when considering QLC vs TLC, yes, the latter has a lower risk of issues, but a high-quality QLC drive also has great longevity, the difference between the two comes at a dramatic cost.

While the P4510 is the better drive (if you have a U.2 connection), it costs nearly twice the price! For most users, we’re not sure if it’s worth the extra. Drives with significantly less TBW than the Samsung 870 are used by millions of people for operating systems, games, and more.

For this very reason, the P4510 and its specs are designed for enterprise/server usage, which almost feels like an acknowledgment from Intel themselves that the mainstream QLC drives are a worthy option for the average consumer.

If however, you’re working in a demanding environment that will require lots of data overwriting and the lowest risk possible for an 8TB SSD (production users, business-critical infrastructure/VMs, etc.) or you simply want the best 8TB drive regardless of cost, then the P4510 8TB is absolutely the best option for you.

Alternative Cheap External 8TB SSD: U32 Shadow

If the VectoTech Rapid is not available, the U32 Shadow from Oyen Digital is a fantastic external SSD alternative.

There isn’t much separating the Rapid vs the Shadow, with identical warranties, similar temperature maintenance, sizes, and durable aluminum bodies; despite not coming from household names like Samsung & Intel, they are decent USB-C gen2 SSDs (both with Thunderbolt 3 capability).

So why do we think the Rapid is better? Well, speed-wise, benchmarks seem to suggest the Rapid can performance slightly faster (in the region of +2.5%, like we said, not much difference!).

Additionally, and perhaps more importantly for most, the Rapid has been on the park for longer, with a larger user base citing its longevity than the U32 Shadow’s limited (but positive) reception.

Given that, at the time of reviewing, the SSDs are identical in price, we think these fine-tuned differences are significant enough that it’s worth going for the Rapid.

But as a second option, whether the Rapid is sold out or temporarily price-gouged, we still highly recommend the U32 shadow as an alternative budget external 8TB SSD.

Best Cheap Enterprise 2.5″ SSD: Micron 5210 Ion

As far as consumer-grade SSDs go, we think the Samsung QVO fits the bill perfectly for all 2.5″ SATA users.

If however, you’re building a large-scale enterprise solution but don’t need the incredible speeds and rewriting capacity of the premium Intel offering above, the Micron 5210 Ion fits the gap nicely.

With up to 540 MB/s read & 360 MB/s write speeds, the 5210 is a decent runner for many operational environments as far as SATA drives go.

You’ll notice the write speeds are significantly lower than our top Samsung SATA SSD, this is because the Ion is designed for a balance between value and endurance by not just basing itself on QLC and the notion of low re-write expectations (i.e. this isn’t the best drive to do tons of writing on, and is instead better for static data where possible).

With that in mind, the 5210 Ion achieves a mean time to failure of 2,000,000 hours, a great feat that wouldn’t be possible without its low write-focus setup.

While we wouldn’t recommend the drive over the 870 QVO for mainstream users & gamers, if you’re building a server farm that will include storage for needs of low re-writes like long-term documentation, static and static VMs, you will likely appreciate the excellent value of this cheap 8TB SATA SSD.
