How to upgrade Steam Deck SSD FAQ

People undoubtedly have questions when it comes to the Steam Deck’s SSD, so I’ve rounded up the most commonly asked questions and provided answers.

What SSD is compatible with Steam Deck?

Both the Steam Deck LCD and Steam Deck OLED both have a PCIe 3.0 M.2 NVMe SSD slot, which is ideal for the smaller SSD size. As such, the WD_BLACK SN770M NVMe is an ideal SSD for the Steam Deck and many other gaming handhelds. It’s available in 512GB, 1TB, or 2TB capacities.

Should I backup my Steam Deck before upgrading the SSD?

Yes. It’s a good idea to clone or back up the old Steam Deck SSD before replacing it with an upgrade. That way, your game data for sure won’t be lost.

What size SSD should I put in Steam Deck?

While there are 512GB SSDs out there, you’ll be better served if you go for a 1TB or 2TB SSD. More storage capacity means there is room for more games, which will make it so you don’t have to rearrange your storage space nearly as often.
