Lexar 1TB Play M.2 2230 SSD, Up to 5,200MB/s Read, PCIe 4.0

Built for the same job as the Western Digital WD_Black SN770M 1TB M.2 2230 NVMe SSD for Gaming: a single-sided M.2 2230 replacing the small factory drive in a Steam Deck, ROG Ally or comparable handheld. It uses TLC flash rather than QLC, which holds up better under repeated rewriting of the same game library.

There is no onboard DRAM, so sustained writes lean on the host. Confirm your device takes 2230 and not 2242 before ordering — the two do not substitute.
