Choosing the best Steam Deck SSD is a sure-fire way of increasing your internal storage on your Steam Deck without compromising on performance. Unlike going with one of the best micro SD cards for Steam Deck, though, an SSD is a more permament solution that replaces your Steam Deck’s original SSD (if present) with a larger (and often faster) option. It also makes for a perfect upgrade if you’re going to be sinking some funds into the new Steam Deck OLED, and you want to maximise your storage right from the off.
All these drives have one big thing in common – their smaller form factor. Each of the drives listed below are M.2 2230 drives, meaning they are designed to fit in smaller spaces, such as inside the Steam Deck, or ROG Ally, or similar handheld consoles. Note that the Steam Deck is limited to PCIe 3.0 speeds, but it happily accepts PCIe 4.0 drives too – you just won’t be accessing their full potential. Later handhelds like the ROG Ally and Legion Go, on the other hand, offer PCIe 4.0 support and therefore will see increased speeds.
It’s worth noting also that the installation process is a little fiddly, but perfectly achieveable with a little patience and this handy iFixit guide that explains it all.

The £111/$130 Kingston NV3 2230 2TB is our current go-to recommendation for Steam Deck and original ROG Ally owners, as it provides a ton of extra space at a very minimal cost – while also coming from a brand that most gamers ought to have heard of. With up to 6000MB/s of sequential reads and 5000MB/s of sequential writes on tap when connected to a PCIe 4.0 interface, this is also one of the fastest 2230-size SSDs available.
Best Sabrent Steam Deck SSD: Sabrent Rocket 2230 1TB
The £95/$90 Sabrent Rocket 2230 1TB makes for an excellent SSD to slot into your Steam Deck, and for what seemed like a while, was actually one of the only options that presented itself.
On paper, the Rocket 2230 is quite a quick option, offering sequential speeds of up to 5000MB/s and random speeds of up to 800K IOPS with its PCIe 4.0 interface. With this in mind, it is limited by the Gen 3 speeds available on the Steam Deck, but even with this, it should offer some especially strong results – around 3500MB/s and 450K IOPS – that eclipse the default 512GB drive, which we measured at 2300MB/s and 110K IOPS.
This drive is available in a wide range of capacities, with the largest being the 1TB model we’ve linked here, but if you want to go smaller for whatever reason, Sabrent also offers 256GB and 512GB options.
Best Corsair Steam Deck SSD: Corsair MP600 Mini 1TB
The £78/$90 Corsair MP600 Mini 1TB makes for another excellent SSD to pair with your Steam Deck, and is one we’ve seen subject to a few discounts at the time of writing.
Its speeds at up to 4800MB/s for sequential reads and writes make it a little slower than the Rocket 2230 above, but this is still more than snappy enough for your Steam Deck. Its random perfomance at up to 850K IOPS for reads and 1.1M IOPS for writes is better though, providing some especially snappy load times to get you into games quicker. With this in mind, the MP600 Mini will be limited by Gen 3 speeds, but it’s still a quicker option than the internal drive already inside the Steam Deck, and is actually tenfold faster than the sluggish 64GB of eMMC storage inside the base model.
As for different capacities, the MP600 Mini is available just in a 1TB config, but that’s still going to be a worthy upgrade, especially if you’ve got one of the lower capacity options.
Best Micron Steam Deck SSD: Micron 2400 2TB
The £137/$146 Micron 2400 2TB marks out one of the newer entries into the world of Steam Deck entries that’s become available since mid-2024, and is also seemingly one of the only drives to be available in a larger capacity.
