Installing an SSD in your PC is one of the most important upgrades you can make. Not only do SSDs make Windows feel faster and more responsive, but they also dramatically speed up game loading times as well. To help you buy the best SSD for gaming, I've put together this handy guide. I've tested dozens of SSDs over the years, and I've picked out my top recommendations below. Regardless of whether you just need some space for that all-important game download or you're about to build a new PC from scratch, here are the best SSDs for gaming you can buy today.
It's never been more important to have one of today's best SSDs for gaming sitting inside your PC. SSDs are much faster at opening, saving and transferring files around on your PC than traditional hard disk drives (or HDDs), which means faster loading times for games and less time spent waiting around.
There are two types of gaming SSD you might want to consider: SATA drives and NVMe SSDs. SATA drives are small, 2.5in drives that plug into a SATA port on your PC's motherboard. They also need to be connected to your PC's power supply. NVMe drives, on the other hand, are even smaller and use an M.2 port on your motherboard. These draw power directly from your motherboard, so they don't need to be connected to your PSU. Most modern ATX motherboards have at least two M.2 ports these days, but some higher end boards can support up to three. Smaller micro-ATX boards, however, may only have one.
SATA drives are much faster than HDDs, but NVMe drives are faster still. They tend to be more expensive as a result, but there are still plenty of good cheap NVMe drives out there that don't break the bank. However, it's also worth bearing in mind that NVMe drives are increasingly falling into two sub-categories: those that support PCIe 3.0, and those that support the newer PCIe 4.0 standard. PCIe 4.0 is twice as fast as PCIe 3.0, and many of the upcoming storage technologies due to hit PC in 2021, such as Microsoft's DirectStorage tech, will utilise this extra speed to help cut down game loading times even further. PCIe 4.0 SSDs are still very expensive, though, and are only compatible with a handful of motherboard chipsets. As such, I wouldn't make them a priority in your SSD upgrade plan just yet, although they will become increasingly more important as the months draw on.
You'll find more information about everything you need know about buying an SSD at the bottom of this page, including what the differences are between SATA and NVMe SSDs, what kind of size SSD you should go for, as well as how to install your SSD inside your PC.

Best gaming SSD 2021
- WD Blue SN550 - the best value NVMe SSD for gaming
- WD Black SN850 - the best PCIe 4.0 NVMe SSD for gaming
- Samsung 860 Evo - the best SATA SSD for gaming
- Samsung 870 Qvo - the best big SATA SSD for gaming
WD Blue SN550
The best value NVMe SSD for gaming
Traditional 2.5in SATA SSDs like the Samsung 860 Evo are great, but if you've got a motherboard with an M.2 slot then you should absolutely go for the WD Blue SN550 as your primary SSD drive.
It's the successor to the excellent WD Blue SN500, and now comes in larger 1TB and 2TB size capacities as well, making it a great option no matter what kind of size you're looking for. Simply put, the WD Blue SN550 is fantastic value for money. It's got great random read and write speeds - better than almost every other budget NVMe SSD out there - and doesn't cost that much more than the best budget SATA SSDs, either. Its random write times are particularly nippy, beating Samsung's more expensive 970 Evo Plus and coming second only to WD's flagship Black SN750.
The 970 Evo Plus and Black SN750 have mildly better random read speeds, but they're also a lot more expensive than the WD Blue SN550. As a result, I think most people would be perfectly happy saving themselves a bit of cash and opting for the SN550 instead. It's also brilliant at handling larger workloads, making this a brilliant all-round SSD for your gaming PC. If you've got a motherboard that supports it, this SSD should definitely be at the top of your list.

WD Black SN850
The best PCIe 4.0 NVMe SSD for gaming
PCIe 4.0 SSDs are still very new and rather expensive, but if you're looking for the best of the bunch, the WD Black SN850 is currently the one to beat. If you thought the speed jump from SATA to PCIe 3.0 NVMes was big, the Black SN850 offers a similar boost again over PCIe 3.0 drives, offering substantially faster read and write speeds across the board.
In truth, its random read times are much the same as the similarly nippy Samsung 980 Pro, but what sets the SN850 apart from other PCIe 4.0 drives is its exceptionally fast write times and transfer speeds. The SN850 is considerably faster than the 980 Pro in this regard, and it's cheaper, too (albeit only marginally), giving you a better value drive overall.
That said, I wouldn't advise rushing out to buy a PCIe 4.0 SSD right this second unless you've got a recent AMD-based PC and are absolutely desperate for the latest and greatest. Intel will be adding PCIe 4.0 support to their 11th Gen Rocket Lake CPUs, which are due out before the end of March, by which point prices may well have started to come down a bit. The WD Black SN850 is definitely the fastest PCIe 4.0 SSD out there right now, but I'd hold off on buying one until they're a bit more affordable.

Samsung 860 Evo
The best SATA SSD for gaming
When it comes to buying an SSD for gaming, a lot people still opt for a 2.5in SATA drive rather than a super fast NVMe SSD, if only because the latter tend to be quite expensive and you need a motherboard that supports them. For SATA SSD hunters, then, the Samsung 860 Evo is hands down the best SSD for gaming you can buy today. Its random read speeds are just as fast as its recently-released successor, the Samsung 870 Evo, and it's also nippier than any other SATA SSD that's crossed my testing bench.
In fairness, Crucial's MX500 is another good budget option for SATA buyers, but when prices for the 860 Evo are only a fraction more thes days, there's little point opting for the MX500 unless you can find it for a substantial discount. What's more, the 860 Evo also comes with a much higher endurance rating than the MX500: 300 terabytes written (TBW) for the 500GB model as opposed to just 180TBW on the 500GB MX500. It's fast, durable and I've yet to see another SATA SSD beat it when it comes to overall value.

Samsung 870 Qvo
The best big SATA SSD for gaming
In fact, there is one SSD with faster write speeds than the Samsung 860 Evo, and that's Samsung's 870 Qvo. Made from 4-bit MLC V-NAND instead of 3-bit MLC like its Evo counterparts, the 870 Qvo is much better value than Samsung's equivalent Evo drives. Its performance is more or less identical, and it's a heck of a lot cheaper, too. As such, if you're looking to get an SSD that's at least 1TB in size but don't want to fork out loads of cash (either on an expensive NVMe SSD or a high capacity SATA drive), the 870 Qvo is the way to go.
Like the rest of Samsung's drives, the 870 Qvo has exceptional endurance ratings and warranties, and its random read and write times are up there with the very best. Plus, if you've got enough cash, you can buy one that's a whopping 8TB - which is practically unheard of in SATA circles. It's still not as cheap as buying a large hard disk drive, but it's the best you're going to get on an SSD.

SATA SSD vs NVMe: what's the difference?
2.5in SATA SSDs: The easiest drop-in replacement for a standard hard disk is a 2.5in SATA model. These are the same size and shape as a standard 2.5in hard disk, and plug into a normal SATA port on your motherboard. Most modern PC cases have mounting points for 2.5in hard disks, often on the back of the motherboard tray. If yours doesn't, you can use a cheap adaptor (really just a 3.5in-wide metal plate with screw holes) to fit the SSD in a normal 3.5in hard disk bay.
To avoid crippling the SSD's performance, make sure you plug the SSD into a SATA 3 port on your motherboard, rather than use SATA 2. SATA 3 SSDs will work in SATA 2 ports, but you'll likely lose around half the SSD's performance. That said, SATA 3 is an interface that's been around since 2009, and one that isn't quick enough to cope with the fastest modern SSDs. For most users, a SATA 3 SSD will be fine, and still several times faster than a mechanical hard disk, but if you've got a motherboard with an M.2 slot that supports NVMe SSDs, you should definitely consider opting for an NVMe SSD instead.
NVMe SSDs: If you're in the market for a super-fast SSD that won't be encumbered by its interface, you need to move beyond SATA to NVMe (also called PCI Express, PCIe NVMe, or just NVMe). Most NVMe SSDs are mounted directly to the motherboard in an M.2 slot. If your motherboard doesn't have such a slot, there's only one way to unleash the speed: a PCIe add-in card (AIC). These add-in cards will fit in a spare PCIe x4 or x16 slot and are monstrously quick, as well as monstrously expensive.
If you have a newer motherboard with an M.2 slot, an NVMe SSD is a neater way to add super-fast PCIe storage. Most NVMe SSDs are just 22mm wide and 80mm long (so about a third shorter than a stick of RAM) and screw straight into the motherboard - no more having to route SATA and power cables around your case.
However, the M.2 standard is a little complicated, chiefly due to its versatility. For starters, there are several sizes of M.2 card, such as 2280 and 22110: the first two digits denote the card's width in mm, and the remaining numbers are the card's length. Fortunately, the majority of consumer NVMe SSDs are the 2280 size. What's more, as well as PCIe storage, the M.2 slot can also support SATA SSDs. These don't have the performance advantage of NVMe drives, but score for neatness, and are about the same price as 2.5in SSDs. Check what standards your motherboard supports, as PCIe SSDs will not work in SATA-only slots and vice versa.
The good news is that many motherboards support both NVMe and SATA M.2 SSDs, giving you the versatility to choose between fast-but-expensive NVMe and slower (but still fast) and cheaper SATA. Bear in mind that the claimed speeds are for sequential transfers, rather than random reads and writes, so should be considered a best-case scenario. It's also worth looking at a drive's IOPS, or input/output operations per second, rating. This isn't always listed in an SSD's specifications, but it can make a big difference to an SSD's real-world performance. A drive with a high IOPS rating can perform many more data reads and writes per second than a lower-rated model, which can make a huge difference in the complex data transfer tasks required by a modern operating system.
What size SSD should I buy?
The minimum SSD size I'd recommend these days is 250GB, as this will give you enough room for your Windows installation (around 20GB), a couple of big games, plus all your music, photos and any other programmes you might need. However, if you have a particularly large photo and music collection, or just like having lots of games installed at the same time, then I'd recommend bumping it up to the 500GB mark.
If you like having most of your games installed at the same time, though, consider finding the cash for a 1TB SSD, or two 500GB SSDs. If you need installing more than one SSD, then have a read of our How to install an SSD / HDD guide.
