Know before you buy
The WD_BLACK SN770M uses the M.2 2230 form factor, which is the standard size for most popular handheld gaming PCs like the Steam Deck and ASUS ROG Ally. We recommend checking your device's manual to confirm it supports M.2 2230 NVMe drives before purchasing.
Yes, this SSD is fully compatible with Microsoft DirectStorage. This technology allows your graphics card to load game data directly from the drive, significantly reducing load times in supported titles.
The Western Digital Dashboard software is designed specifically for Windows. If your handheld device runs Windows, you can use the software to monitor drive health and update firmware; however, it will not function on SteamOS or other Linux-based handheld operating systems.
Yes, the SN770M is backward compatible with PCIe Gen 3.0 slots. Keep in mind that your transfer speeds will be limited to the maximum bandwidth of the Gen 3.0 interface rather than the drive's peak 5,150 MB/s.
nCache 4.0 is Western Digital's proprietary caching technology that optimizes write performance. It helps the drive maintain high speeds during heavy tasks, such as installing large game files or moving data, ensuring your system remains responsive.
