Carry the Whole Library on a Handheld, Not Just This Week's Four Games
A Steam Deck or ROG Ally fills up fast once modern titles run past 100GB each, and the fix is not a bigger microSD card. It is the 2230-size NVMe slot inside the device. The SN770M is a full PCIe Gen 4 x4 drive built in that M.2 2230 footprint, so 2TB of TLC 3D NAND fits where the factory drive sat, at up to 5,150 MB/s read and 4,850 MB/s write. Western Digital pairs it with nCache 4.0 and Microsoft DirectStorage support for faster installs and level loads. Compare it against the rest of the solid state drives range at Island Electrical Supply.
Where It Fits
- Handheld gaming devices including the Valve Steam Deck and ASUS ROG Ally, where the 2230 length is the limiting factor.
- Compact laptops built around M.2 2230 slots, including many Microsoft Surface and Dell models.
- Large game libraries, since 2TB removes the constant install-and-delete cycle that a 512GB device forces.
- Sustained workloads, backed by 1,200 TB written of rated endurance and a five-year limited warranty.
What It Delivers
- Up to 5,150 MB/s read and 4,850 MB/s write over PCIe Gen 4.0 x4.
- 650,000 random read IOPS and 800,000 random write IOPS, which is the figure that governs how quickly many small game assets load.
- Microsoft DirectStorage support and Western Digital nCache 4.0 write caching.
- Weighs a tenth of an ounce at 1.2 inches long, so it adds nothing to a handheld's thermals or balance.
- Western Digital Dashboard software for health monitoring and firmware, on Windows.
