When Sony first released the PlayStation 5, it wasn’t possible to expand the console’s storage. Thankfully, that changed with a software update that the company pushed out less than a year later. And with how big some game installs have become in recent years, it’s a good thing, too: the PS5’s built-in 667GB of space may have been good enough in the system’s first year, but now, the default drive is absolutely limiting.

The good news is a standard PCIe Gen4 x4 M.2 NVMe SSD can solve all of your PS5 storage woes. If that mess of acronyms has you recoiling, don’t worry: you’ll see that it’s not all that complicated. And if all you want to know is what the best PS5 SSDs are, we’ve got them right at the top.

Best PS5 SSDs in 2025

How we test PS5 SSDs

I’ve tested most of the SSDs recommended on this list, either for PS5 or computer use. I also bought and used our top pick in my own PS5.

How much PS5 storage do I need?

The PlayStation 5 and PlayStation 5 Pro can accept internal drives with between 250GB and 8TB of storage capacity. If you already own a PS5, chances are you have a reasonable idea of how much storage you need ​​for your game library. If you’re buying an SSD with a new PS5 or PS5 Pro, or buying for someone else, it’s more difficult to tell what you might need for a high-performance experience.

PS5 games are smaller on average than their PS4 equivalents, typically taking up between 30GB and 100GB, with some notable (and very popular) exceptions. If you’re a fan of the Call of Duty series, installing Black Ops 6 and Warzone 2.0 can eat up to 240GB. In other words, a full Call of Duty install will take up more than one-third of the PS5’s internal storage. If you’re not a CoD fan, though, chances are you’ll be good to store between six to 10 games on a regular PS5 internally before running into problems.

You also need to consider your internet speed. If you live in an area with slow broadband, the “you can just download it again” rationale doesn’t really work. At my old home, a 100GB download took me around eight hours, during which time it was difficult to simultaneously watch Twitch or, say, publish articles about upgrading PS5 SSDs. Keeping games around on the off-chance you’ll want to play them at some point makes sense.

Off the bat, there’s basically no point in going for a 250GB PS5 SSD. Economically, 250GB drives aren’t that much cheaper than 500GB ones — and practically, that really isn’t a lot of space for modern games to live on. 500GB drives can be a decent option, but after years of declining prices, I think the sweet spot for most people is to opt for a high-capacity 1TB or 2TB drive, which should run you at most $200. The latter will more than double the PS5 Pro’s storage without breaking the bank.

Unless you’re rolling in cash and want to flex, 4TB and 8TB models should mostly be avoided, as you’ll end up paying more per gigabyte than you would with a 1TB or 2TB drive.

While the 825GB PS5 only provides 667GB of storage, that’s largely due to storage being reserved for the operating system and caching. If you install a 1TB PS5 SSD, you’ll have, within a margin of error, 1TB of storage available for games. Out of the box, the PS5 Pro offers 1.86TB of storage for games, though you can eke out more if you delete the pre-installed Astro’s Playroom (gasp).

Since neither the PS5 Slim nor PS5 Pro feature updated CPU architecture, all of our recommendations will work with whatever PS5 model you own.

Can you play PS5 games on an external SSD?

External hard drives tend to cost less than internal SSD counterparts (and there’s a good chance you might own one already). Unfortunately, there are restrictions on what you can do with them. An external SSD connects to your PS5 via USB, and is only suitable for playing PlayStation 4 games, or storing PS5 titles. That’s useful if you have anything but the best high-speed internet — it’s faster to move a PS5 game out of “cold storage” on an external drive than it is to re-download it — or want to keep your PS4 library on hand.

Due to the limitations here, you don’t need the highest-performing model, although you should opt for SSDs over HDDs for improved transfer speeds and load times. Any basic portable drive from a reputable brand will do, with the Crucial X9 Pro and Samsung T7 being options we’ve tried and can recommend.

Which SSD cards are compatible with the PS5?

The official answer to this question is an “M.2 Socket 3 (Key M) Gen4 x4 NVME SSD.” But even within that seemingly specific description, there are additional factors to consider. The main requirements Sony has laid out for compatibility come down to speed, cooling and physical dimensions.

For speed, Sony says drives should be able to handle sequential reads at 5,500MB/s. Early testing showed that the PS5 would accept drives as slow as 4,800MB/s, and that games that tap into the SSD regularly — such as Ratchet & Clank: Rift Apart — would cause no issues. Pretty much the only thing the PS5 will outright reject is one that doesn’t match the Gen4 x4 spec.

In our opinion, though, using a drive slower than the specification is a risk that, if you don’t already have that drive lying around, is not worth taking. Just because we haven’t found issues yet doesn’t mean there won’t be games that could be problematic in the future. The price difference between these marginally slower Gen4 drives and the ones that meet Sony’s spec isn’t huge, and you might as well cover all your bases.

Slightly more complicated than speed is cooling and size. Most new SSDs are going to be just fine; the PS5 can fit 22mm-wide SSDs of virtually any length (30mm, 40mm, 60mm, 80mm or 110mm, to be precise). The vast majority of drives you find will be 22mm wide and 80mm long, so no problem there.

It should be noted that the system can fit a 25mm-wide drive, but that width must include the cooling solution. Speaking of, Sony says SSDs require “effective heat dissipation with a cooling structure, such as a heatsink.” The maximum height supported by Sony’s slot is 11.25mm, of which only 2.45mm can be “below” the drive.

This previously meant some of the most popular heatsinked Gen4 SSDs, including Corsair’s MP600 Pro LP, would not fit within the PS5’s storage expansion slot. Since Engadget first published this guide in 2021, most NVMe makers, including Samsung, have come out with PlayStation-specific models that meet those requirements. That said, if you want to save some money, bare drives are often cheaper and it’s trivial to find a cooling solution that will work for the PS5.

The only component in an NVMe SSD that really requires cooling is the controller, which without a heatsink will happily sear a (very small) steak. Most SSDs have chips on only one side, but even on double-sided SSDs, the controller is likely to be on top, as manufacturers know it needs to be positioned there to better dissipate heat.

So, head to your PC component seller of choice and pick up basically anything that meets the recommended dimensions. A good search term is “laptop NVME heatsink,” as these will be designed to fit in the confines of gaming laptops, which are even more restrictive than a PS5. They’re also typically cheaper than the ones labeled as “PS5 heatsinks.”

One recommendation is this $6 copper heatsink, which attaches to the PS5 SSD with sticky thermal interface material. It works just fine, and in performing stress tests on a PC, we couldn’t find anything metal that didn’t keep temperatures under control. When you’re searching, just make sure the solution you go for measures no more than 25mm wide or 8mm tall (including the thermal interface material) and has a simple method of installation that’s not going to cause any headaches.

One last thing: When shopping for a PS5 NVMe, there’s no reason to buy a Gen5 model over a more affordable Gen4 model. As things stand, Sony’s console can’t take advantage of the new standard, and though Gen5 drives are backward compatible, they’re more expensive than their Gen4 counterparts. Just buy the fastest and highest-capacity Gen4 model you can afford.

How to install an SSD into your PS5

If you need guidance on how to install your new NVMe into your PS5 or PS5 Pro, we have a separate guide detailing all the steps here. Installation is pretty straightforward, but our how-to can help you if you’re stuck. Just make note: Before attempting to add more storage via a PS5 SSD, ensure that you have Sony’s latest software installed.
