Best M.2 SSDs for gaming in 2024

Experience lightning-fast loading screens with the best M.2 SSD for gaming. This reliable upgrade enhances your day-to-day PC usage, as not only does an M.2 NVMe SSD provide a much faster overall experience than other types of drive, but it's also one of the most affordable upgrades you can make for your PC. 

The best M.2 SSD for gaming on the market is the WD Black SN850X. It comes with a great blend of performance and affordability that's great for PC gaming. However, when it comes to affordability we're also big fans of the supremely good-value and surprisingly fast Lexar NM790 , which makes our top recommendation for the best budget M.2 SSD.

We're constantly conducting extensive testing to identify the top NVMe SSDs for PC gaming. While a 512GB drive may seem tempting for the money, it may not be worth it given the size of modern PC games, so 1TB to 2TB is considered something of a sweet spot. We still recommend Gen 4 drives over Gen 5, as currently there's little real world advantage over the latest versions, but if that changes we'll update this guide to reflect it.

The 1TB version is a great shout if you're after an affordable, but fast, SSD. But the 2TB drive is a decent price with regular discounts that often price it below the competing Samsung or SK Hynix drives.

Buy if...

✅ If you want a great all-rounder: The SN850X has a winning combination of great speeds, cool running and affordability that's difficult to beat.

If you don't want to worry about temps: Whether you go for the heatsink model or not, the WD Black SN850X stays chilled out. 

Don't buy if...

You want the absolute cutting edge of performance: There are slightly faster drives, or much faster if you go for Gen 5, but realistically this is all the real-world speed you're going to need for the time being.

The regular SN850 was one of our favourite drives, but since the WD Black SN850X arrived it took our top spot for the best NVMe SSD overall, and has stayed there ever since.

So what sets it apart from the pack? Well, while it might have some of the standard features of a regular Gen 4 NVMe drive, what with its four lanes of PCIe connectivity and the expected M2 2280 form factor, it sports some shiny new additions to the board that add some serious performance credentials.

WD's own controller has had some revisions, alongside an upgrade from 96-layer TLC NAND memory chips to newer 112-layer models. And if those sort of specs make your eyes cross, have no fear, for we shall interpret them for you: It means performance. Lots and lots of it.

The 1TB model delivers read speeds of 6,300MB/s, and write speeds of 7,300MB/s. That's plenty fast, and while it puts it in contention with some of the very faster Gen 4 drives we've tested, there are slightly faster. Two things on that point: Firstly, when it comes to small differences in synthetic SSD benchmarks, you're absolutely not going to be able to tell the difference in real world drive usage. And two? 

With the WD Black SN850X, you're not just getting great speeds, you're getting the whole package.

Let's talk temperatures for a moment. Simply put, like many components, if your NVMe gets too hot under sustained usage then it throttles itself back to save itself from potential damage. The WD Black SN850X, however, runs remarkable cool under load, particularly if you pick the model with the WD signature armour-style heatsink.

We found our review unit never breached 58°C under sustained load, which is a big improvement over the standard SN850 and its 77°C. 

That should give some peace of mind that you're getting the best performance out of your drive even under heavy usage, although even the non-heatsink model performs decently when it comes to temperature throttling.

You also get WD's Game Mode drive management software. The company claims this improves your gaming load times thanks to some clever algorithms. Pretty hard to test, that one, but we found the WD Black SN850X did extremely well in our game loading benchmarks, so it may very well be adding something to the pot. A nice feature to have, at the very least.

And finally, there's price. While the Lexar NM790 below can often be found cheaper and still makes our best budget recommendation for the excellent performance it provides, the WD Black SN850X has been around for a little while now, and goes on discount on the regular. You might have to wait around a bit to find the best deal, but they are out there, and all the sweeter for it.

Any drawbacks? Well, the 4K random access results weren't stellar, although you'd only really see that on the benchmarks. It's real world performance you're likely to care about most, and here the SN850X performed brilliantly.

It's an all-round performer, and a completely solid overall choice for anyone looking for an NVMe SSD that hits all the right notes. Cool, efficient and plenty fast. What more do you really need?

Fast, affordable and from a respected brand, and it even runs cool to boot. As budget performers go, you don't get any better than the little Lexar, and we were mightily impressed when we gave one a review.

Buy if...

✅ If you want top end performance for less: The Lexar NM790 is damn near as fast as the top Gen 4 performers, but regularly comes in significantly cheaper

If you don't want a heatsink: We tested the heatsink-less model, and found its thermal performance was great, making it a very good laptop or small form factor solution.

Don't buy if...

You'd prefer some more known components: The controller and flash combination here is a bit of an anomaly, but we've had no problem with the drives we tested and are still using long term. Still, if cheaper components bother you, you might want to look elsewhere.

Cheap and cheerful? How about cheap and still delivering excellent performance? The Lexar NM790 is a fantastic SSD that makes very few compromises while still remaining very affordable, and that means it sits proudly as our top budget NVMe drive recommendation.

If you're in the market for a budget NVMe SSD, chances are you've been working under the assumption that you'll have to take some performance penalties in order to save some cash. Not so with the Lexar NM790, as it delivers read and write speeds that any Gen 4 drive would be proud of.

Rated at 7,400MB/S sequential reads and 6,500 writes, this drive impressed us mightily when we reviewed the 4TB version, but you'll be pleased to find it comes in a range of capacities including a very attractively priced 1TB model. But how come you can get all this performance and capacity for less?

Well, it comes down to the use of a lesser known controller and flash memory combo, the MaxioTech MAP1602 and YMTC 232-layer TLC respectively. Before you start worrying that maybe these lesser known components will under-perform however, allow us to put your minds at rest. While the Lexar has made some concessions in the name of budget, when it comes to performance, it stands alongside some of the very best drives we've tested. 

Whether its synthetic benches or real world gaming tests, the NM790 performs admirably, all the while running cool, calm and collected. It makes use of a large SLC cache buffer that allows it to put in numbers that compete with the best Gen 4 drives, and that's a very neat party trick to bring to the table.

More than that, the Lexar makes for an efficient drive no matter which way you look at it. While there are heatsink models available, we tested the heatsink-free version and found that its thermal performance was admirable, which is no mean feat, so there's really no need to spend up unless you really want to make double-sure that it'll deliver its full speeds without throttling.

Every now and then a component arrives that, thanks to some clever lateral solutions, runs rings around a lot of the competition while delivering great performance for less cash, and that's exactly what we've got here. We regularly see 1TB models retailing for around $80 and 2TB models around the $130 marker, and that's a genuine bargain for such a performant SSD.

Not only is it a budget champion, the mighty Lexar, but it can keep up with the big names without breaking a sweat.

It might not have the brand recognition of its rivals, but the Nextorage NVMe SSD has a truly remarkable amount of performance and capacity, and can be found for very good prices too. This version comes with a substantial heatsink, but versions without are available for small form factor and laptop applications.

Buy if...

✅ You're looking for oodles of space: The Nextorage NEM-PA comes in a variety of sizes, but we particularly like the 2TB and 4TB versions for the money. Speaking of which...

You don't want big prices for big sizes: We see the Nextorage drives on discount all the time, however, even at regular retail prices they represent huge value for money.

Don't buy if...

You want high speeds from every possible angle: The Nextorage NEM-PA drives have absolutely fantastic real-world performance, but benchmark hounds will notice the 4K numbers and PC Mark synthetic results are a little behind the pack.

Looking for lots and lots of storage, with no compromises on performance and for a great price? You'd struggle to do better than this Nextorage drive, which comes in a variety of well-priced high-capacity specifications, making it an easy pick for the best high-capacity NVMe drive in this list.

If you're unfamiliar with the name, we don't really blame you. In a market dominated by big players with heavy brand recognition, Nextorage is still the new kid on the block, although make no mistake, it still comes with a pedigree you might not expect.

See, Sony initially created Nextorage to manufacture SSD drives for its PlayStation consoles, until Phison, creator of some of the fastest storage controllers in the business, took a controlling stake in the company. 

Soon after, Nextorage debuted drives making use of the Phison E18 controller, and it's the very same chip that graces some of the fastest drives we've had the pleasure to review.

So, as you'd expect, this drive is quick. Very quick. We tested the 2TB model and found that it was an excellent performer, demonstrating read and write speeds that put many drives to shame. It's rated for 7,300MB/s reads and 6,900MB/s writes and delivers them with aplomb, but it also managed to sustain 625GB of writes before dropping performance, thanks to the fact that a full one third of the NAND flash can be used in high-speed SLC cache mode. 

Still, it's not just performance you're looking for here, its capacity, and when it comes to the 2TB and 4TB versions of these drives performance remains very similar between the two, while also often demonstrating a very competitive price compared to the closest competition.

SSD prices have been on the rise recently, but we still regularly see these capacious drives at prices that make you do a double-take. That makes them a fantastic way of adding huge amounts of lightning-fast storage capacity to your machine without breaking the bank.

You'll find variants using very substantial heatsinks and some with none at all, but if you've got the room for it in your machine we're happy to report that the heatsink version runs remarkably cool. Still, if you're looking for something more compact then the heatsink-less models should still run plenty cool, which means they'll be delivering great performance even in a laptop configuration.

Big storage, big performance, very competitive prices. Yep, Nextorage may not have made a name for itself just yet, but with this sort of hardware, it really won't be long.

Flash: 177-layer TLC NAND
Interface: M.2 PCIe 4.0 x4
Seq. read: Up to 5,000MB/s

Reasons to buy

Real world performance trumps the Deck
Smaller capacities don't tank the battery

Reasons to avoid

Inconsistent at 1TB...
and with higher power draw

Our favorite Sabrent Rocket 2230 config:

<a href="" data-link-merchant=""" target="_blank">Sabrent Rocket 2230 | 512GB | 5,000MB/s read | 3,700MB/s writes
The 512GB drive is probably the sweet spot upgrade for anyone with either the 64GB or 256GB Steam Deck. You get both more space for your games as well as faster performance and lower power to help eke out a little bit more battery life.

Buy if...

✅ You're looking for a Steam Deck upgrade: Any of these drives will be faster than the unit in the Steam Deck, and given the prices they make a relatively cheap storage upgrade over buying a high-capacity Deck in the first place.

Smaller models sip power: Given we're talking portable gaming, power draw is an important factor, and it was only the 1TB version that we spotted drinking a little heavily from the battery.

Don't buy if...

You want a 1TB drive with no caveats: Make no mistake, the 1TB version is still an excellent upgrade, but we did get some inconsistent load-time results, and it did drain the battery a little heavier than the others we tested.

If you've taken the plunge and bought yourself a Steam Deck, you may have encountered a common issue: The cheaper Decks make for great gaming machines, but can come with pretty limited storage capacity. 

If you don't mind breaking out a screwdriver and voiding the warranty (you're absolutely sure about this, right?) then there are a few different drives in the 2230 form factor to consider, but we've found no better than the Sabrent Rocket 2230 NVMe SSD, and that makes it our recommendation for the best upgrade for Steam Deck storage.

The Sabrent drives come in 256GB, 512GB, and 1TB capacities and retail at $50, $90, and $170 respectively. That's still a fair bit of cash to pay for these sort of capacities, but given that the competition is priced similarly and you're limited to this form factor, it still represents good value for what you eventually receive.

The 256GB is rated to 4,640MB/s reads and 1,900MB/s writes, whereas the 512GB is meant to be closer to 5,000MB/s reads, and 3,700MB/s writes. The 1TB is a little slower with 4,750MB/s reads, but delivers faster 4,300MB/s write speeds. Each is still quicker than the regular SSD you'd find in a Steam Deck however, and that combined with the increased capacity is really what you're paying for here.

If you're currently slogging away with a 64GB Steam Deck and carefully managing your install options then upgrading to the 256GB or the 512GB Sabrent drive gets you much more capacity and a lot more performance, making it a very worthwhile upgrade, especially when you compare it to the price of buying a larger capacity Steam Deck in the first place.

Mobile gaming has come a long way, but storage capacity is still one of the areas where we could see some reasonable improvements in the default specifications. Get ahead of the curve and do it yourself and you can reap the benefits, and these Sabrent drives make the most sense as worthy additions to your beloved Deck.

<a href="" data-link-merchant=""" target="_blank">Silicon Power 2TB XS70  | 2TB | 7,100MB/s read | 6,600MB/s write
The 2TB model comes at a very competitive price and works well as an expansion drive for the PlayStation 5. With excellent read/write speeds and an attractive and great-performing heatsink, it makes an excellent choice for those looking to upgrade the consoles storage to something faster.

Buy if...

✅ You're looking for the best drive for your PS5 : Several SSDs have been built to fit in a PlayStation 5, but this one stands out with its excellent thermals and speeds despite its small heatsink.

If you want a set and forget solution: The Silicon Power XS70 is a no-fuss solution to a potentially fussy problem. It's an all-round great drive for the PS5 that fits in perfectly with no major caveats.

Don't buy if...

You want included software for a PC install: The XS70 makes for an excellent PC SSD as well, but if you're looking for cloning software or indeed, any SSD software at all, you'll want to find a third-party solution.

While the PlayStation 5 does make use of a rather snazzy Gen 4 drive, there will be many of you hoping to fit your console with something larger to fit as many games as possible on to your shiny console machine of dreams. That being the case, we recommend the Silicon Power 2TB XS70 as our top pick for the best PS5 NVMe SSD.

For a start, it's a superb performer. Thanks to some Micron 176-layer TLC NAND and a controller that needs little introduction, the Phison E18, alongside 2GB of DDR4 RAM, the XS70 makes for a potent drive in any setup with the appropriate M2 slot. 7,300MB/s sequential reads and 6,800MB/s writes puts it well up there with some of the faster drives we've tested, along with some excellent random read performance.

But honestly, if you're just looking for a big and powerful drive to stick straight into your PS5, close the casing and forget about it, you're going to ideally want something designed with PlayStation compatibility in mind, and that's exactly what Silicon Power has created here.

There's no hardware encryption on offer, but really what you need is great performance and well-controlled thermals, and the PlayStation 5 compatible heatsink here is a superb performer in that regard. It's very efficient, and we saw top temps of a mere 63°C, which is a great result for a Gen 4 drive with this level of performance.

It's small packaging reminds us of a flash drive, but when it comes to what this drive is capable of delivering then a simple USB stick this is not. Those of you planning on installing one in a PC may bemoan the lack of software support ecosystem, but console users will care not one jot.

You'll simply want a very fast drive in the right form factor that you can set, forget, and use on the regular to keep your PlayStation stocked with games, and here Silicon Power have really judged the market very well indeed.

It's not big, but it is clever, and if you really want to make the most of your console experience by installing a very fast drive designed to sit right at the heart of your PS5 without a single complaint, then this right here is the SSD for you.

How we test NVMe SSDs

We put every SSD we get in the PC Gamer labs through their paces in various benchmarks made up of a mix of synthetic tests and real-world applications. To ascertain a drives sequential throughput, we use ATTO SSD Benchmark for compressible data (a best-case scenario) and AS SSD for incompressible data (more realistic). We also test random throughput with AS SSD and a combination of CrystalDiskMark 7.0 and Anvil Pro. 

When it comes to the real-world tests, we time how long it takes to copy a 30GB game install across the drive and use PCMark10 and Final Fantasy XIV: Shadowbringers, which includes a level load test. 

We also check operating temperatures to ensure that the drive isn't getting too hot and throttling. That's becoming more of an issue with faster and faster drives. PCIe 5.0 drives appear to require a lot more cooling than previous generations, which does make you wonder if the extra speed is really worth it yet.


Can I fit an M.2 SSD on my motherboard?

The M.2 socket has been included on motherboards of all kinds for many years now, so the chances are that there's a spare slot sitting inside your existing gaming PC. Check out your motherboard's specs page online before pulling the trigger on an NVMe SSD purchase, though, to be sure. Those harboring a board that's a few years old now, do yourself a favor and make sure it supports booting from an NVMe drive first. Not all older motherboards do, especially if you're going back multiple CPU generations (maybe a full upgrade's due, if so).

What is NVMe, exactly?

The NVMe, or Non-Volatile Memory Express interface, has been designed specifically with solid state drives in mind. In contrast, SATA, the previous interface in charge, was built to cater to most HDDs. The thought is, at the time, that no storage would ever need to exceed its lofty max bandwidth. To the surprise of a few, new storage mediums such as solid state absolutely blaze past SATA's max bandwidth, and so a new protocol in NVMe was born. 

That makes NVMe SSDs the perfect storage tech for gaming. 

Running on the same basic interface as your graphics card, NVMe SSDs deliver more raw bandwidth and performance than any SATA-based SSD could ever offer. They're also a lot smaller than any other hard drive or SSD too, which all means that the best NVMe SSDs are perfect for either that small form factor build you always wanted or a monstrous high-end gaming PC build

What PCIe generation should I look for?

Right now, PCIe 4.0 is the go-to PCIe generation. That's because it offers a high speed at a reasonable cost. The newest SSDs on the market offer PCIe 5.0 capability, which doubles the theoretical bandwidth an SSD can run at. However, these are few and far between and awfully expensive. Also the first  drives of any PCIe generation tend to end up much slower than what that generation is truly capable of.

Here are the rough speeds for each PCIe generation over x4 lanes:

PCIe 1.0: 1GB/s
PCIe 2.0: 2GB/s
PCIe 3.0: 4GB/s
PCIe 4.0: 8GB/s
PCIe 5.0: 16GB/s

What's so special about NVMe?

The old storage paradigm was built on the idea of spinning disks. When SSDs hit the mainstream consumer market back in 2007, they reset our expectations for storage. Moving from the mechanical world of hard drives to the silicon world of SSDs brought rapid improvements in performance, technology, capacities, and reliability. SSDs quickly saturated the various SATA connections, and so faster alternatives were needed, but the interface was only part of the problem.

The AHCI (Advanced Host Controller Interface) command protocol was designed for much slower media (i.e., spinning magnetic disks). AHCI is inefficient with modern SSDs, so a new standard was developed: NVMHCI (Non-Volatile Memory Host Controller Interface). Combine NVMHCI with a fast PCIe interface, and you have NVMe, Non-Volatile Memory Express. It's a much-improved interface developed around the needs of flash memory rather than spinning disks.

What's NVMe performance like in the real world?

If you're copying a game from one drive to another or validating game files in Steam, faster NVMe drives make a difference. They can also shave off a second or two when it comes time to load a game level, but the more significant difference is against hard drives, where even a slower SATA SSD is much faster. Go beyond a certain point, and all SSDs start to feel similar.

In other words, while the speed freak in me loves what NVMe brings to the table, I recognize that in practice, it's usually not that noticeable. If you're looking to get the most from your money when it comes time to build a gaming PC, good SATA SSDs remain an excellent option, with prices now falling below 10 cents per GB.

NVMe drives are becoming increasingly commonplace, and prices continue to drop. In the past year, I've tested far more NVMe drives than SATA drives, mainly because SATA drives are all starting to look the same. Most hit the same ~550MB/s limit of the SATA interface for sequential IO, though random IO can still be a bit problematic on some models. With budget NVMe prices now matching SATA drives, most new builds should seriously consider whether the extra power and data cables of SATA are necessary.
