Compact M.2 2230 drive for handhelds

The Micron 2650 256GB internal SSD uses the M.2 2230 form factor, measuring 30mm long, to fit devices such as the Steam Deck, ROG Ally and Microsoft Surface models. It connects through a PCIe 4.0 x4 interface with NVMe 2.0 protocol.

PCIe 4.0 x4 sequential read up to 5000 MBps

The headline specification is a maximum sequential read speed of 5000 MBps over PCIe 4.0 x4, with sequential writes up to 2500 MBps. Random performance reaches 450,000 IOPS read and 500,000 IOPS write. The drive is backward compatible with PCIe 3.0 systems.

176-layer 3D TLC NAND and Host Memory Buffer

Micron's 176-layer 3D TLC NAND provides the storage media, while Host Memory Buffer support uses system RAM for caching instead of a dedicated DRAM chip. This design lowers power draw to extend battery life in portable hosts.

Questions about this item

How fast will the 5000 MBps sequential read feel in a Steam Deck?

Game load screens and level streaming will be noticeably quicker, though the handheld's thermal limits may throttle sustained transfers below the peak figure.

Does the PCIe 4.0 x4 interface run at full speed in a PCIe 3.0 slot?

The drive is backward compatible and will operate at PCIe 3.0 x4 speeds, capping sequential throughput at the slot's lower bandwidth ceiling.

Will the 30mm M.2 2230 board fit a Surface Pro 8?

Yes, the 2230 form factor is the exact 30mm length required by the Surface Pro 8 and similar ultra-thin devices.
