The WD_BLACK SN770M WDS200T3X0G is a 2TB NVMe SSD for expanding storage in compatible handheld gaming devices and laptops that accept an M.2 2230 drive. Its compact format suits compatible systems such as the ASUS ROG Ally and Valve Steam Deck, as well as M.2 2230-compatible Microsoft Surface and Dell laptops.
The drive uses a PCIe Gen 4 interface with up to four lanes and can also work with the PCIe Gen 3 and Gen 2 configurations listed in the datasheet. The 2TB version delivers sequential speeds of up to 5,150 MB/s read and 4,850 MB/s write, helping with game installations and file transfers when the host system supports the required interface.
TLC 3D NAND provides the drive’s storage, alongside Sandisk nCache 4.0 and Microsoft DirectStorage support. Compatibility depends on the host having an M.2 2230 SSD slot.
