This 2TB Micron M.2 2230 SSD is £159 from Amazon right now, and a great choice for your Steam Deck
Update: even cheaper.
We're seeing a flurry of activity on the front of new handheld consoles from the likes of Lenovo and more at the moment, and let's not forget both the Steam Deck and Asus ROG Ally, of course. With these consoles, your only super convenient method of adding storage is to slot in a Micro SD card. But, there is another way, for a more permanent means - changing the SSD.
We recently rounded up the best Steam Deck SSDs and today, one of them is available for a solid price: this 2TB Micron 2400 is down to £159 from Amazon. That's significantly less than other 2TB drives compatible with the Steam Deck.
It's an ideal choice to chuck into your Steam Deck, ROG Ally or similar because it's a smaller form factor. Usually NVMe SSDs are 22x80mm in size (hence the 2280 form factor), but options such as the Micron 2400 are 22x30mm are smaller, and designed to fit into diddy spaces, such as into the Steam Deck or ROG Ally.
As well as being the ideal size, this 2TB Micron choice also provides a solid upgrade in terms of speed. It's rated for max reads of 4200MB/s when hooked up to a PCIe 4.0 port, although you'll probably see closer to 3500MB/s given that the Steam Deck is limited to PCIe 3.0 speeds by virtue of its interface. Regardless, this is still quicker than the Steam Deck's built in SSD with its speeds of up to 2500MB/s, as well as giving you at the most four times the storage compared to the 512GB capacity of the top model. What's more, it's a huge upgrade over the 64GB base model, considering both the amount of storage you're getting, and the fact the base model ships with eMMC storage that's limited to 300MB/s in terms of speed. The Micron 2400 increases that tenfold.
Of course, the only thing to keep in mind with a Steam Deck SSD upgrade is that it's a bit more involved than slotting in one of the quickest micro SD cards for Steam Deck. You'll need to carefully take the Steam Deck apart following this handy iFixit guide, which walks you through accessing the internals, carefully removing a heatsink, disconnecting the battery and swapping the drive. From here, you can use a USB flash drive to reinstall SteamOS. If you've worked on a desktop computer or laptop before, then this isn't any more difficult - it's just a bit fiddlier due to the smaller sizes. I'd say it's still very achieveable, you just need a bit of patience and a few tools!
If you want a lot of speedy storage for your Steam Deck or ROG Ally to put lots of games on, this 2TB Micron 2400 M.2 2230 NVMe SSD for £159 from Amazon is the deal for you.
