Upgrading a Steam Deck means a single-sided M.2 2230 NVMe SSD. The LCD Steam Deck runs the slot at PCIe Gen3, so a cheaper Gen3 or Gen4 2230 drive performs the same in it; the OLED is similar. Single-sided is the key requirement for clearance, and you move the small EMI shield from the old drive to the new one. This table ranks single-sided 2230 SSDs that fit the Steam Deck by live price per terabyte on Amazon.ca.

Frequently asked questions
What SSD does the Steam Deck use?
A single-sided M.2 2230 NVMe SSD. The LCD model's slot is PCIe Gen3, so a Gen3 or Gen4 2230 drive works equally well.
Is a Gen4 SSD worth it in the Steam Deck?
No real benefit on the LCD model, whose slot is Gen3. Buy the best-value single-sided 2230 drive rather than paying for Gen4 speed you cannot use.
Do I need to move the EMI shield?
Yes. Transfer the thin metal EMI shield from the original SSD to the new one before installing, or wrap the new drive as Valve specifies.
