We’re seeing a lot more in the way of small form factor SSDs pop up on the market for use with the seemingly ever-growing sector of handheld games consoles including the likes of the Steam Deck, Asus ROG Ally and more, as people seek to add even more internal storage. If you are one of those peeps, you’ll be pleased to know that one of the best Steam Deck SSDs out there, the WD Black SN770M is marked down to just £135 from Amazon, which is a steal compared to its usual £184 list price.

In terms of speed, the SN770M provides some of the best numbers on this list, with up to 5150MB/s reads and 4000MB/s writes. Even if the actual speeds will be limited by the PCIe 3.0 interface, the SN770M is still capable of offering speedy storage compared to what’s inside the Steam Deck already, whether you’re upgrading from the internal SSD in some models, and especially if you’re bumping up from the base model’s comparably sluggish eMMC storage. Whatever way you cut it, the SN770M represents a major upgrade in terms of speed.

Of course, this is a drive that can be fitted to other handheld consoles such as the Asus ROG Ally, and that’s given its smaller M.2 2230 size, which means it fits perfectly into the 22mm x 30mm drive bay size allowed in these smaller consoles. You can try and use this in a more conventional sized PC if your motherboard supports an M.2 2230 drive, although at this moment, the more standard sized M.2 2280 drives in PCIe 4.0 form are much more powerful for much the same money, and arguably are easier to fit.
