The "P310 Gen4 2280 2TB NVMe PCIe M.2 SSD" from Crucial Technology is not directly suitable for the Steam Deck, as the Steam Deck only supports M.2 2230 SSDs. The Steam Deck has an M.2 slot that is only designed for the 2230 form factor, and mounting an M.2 2280 SSD would cause mounting issues and potentially performance issues.
