Western Digital SN770M NVMe 2TB M.2 2230 PCIe Gen 4.0 5150MB/s Internal SSD

The Western Digital WDS200T3X0G-00CHY0 is a 2TB NVMe solid state drive that fits the compact M.2 2230 slot and communicates through a PCIe Gen 4.0 interface. It is designed to give modern handhelds and thin laptops a large boost in both capacity and speed without taking up extra space.

With sequential read speeds that reach up to 5,150 MB/s and write speeds up to 4,850 MB/s, the drive delivers quick game launches, responsive application loads, and short file-transfer times. Random performance stands at 650,000 IOPS for reads and 800,000 IOPS for writes, so small files move just as smoothly as larger ones.

The M.2 2230 format makes the drive an ideal drop-in upgrade for devices such as the ASUS ROG Ally, the Steam Deck, and ultraportable laptops that rely on this shorter slot. Gamers can carry an entire library without juggling microSD cards, and professionals gain room for large project files while keeping their system light.

An endurance rating of 1,200 TBW provides the workload headroom needed for frequent installs, updates, and large-scale data transfers. Support for Microsoft DirectStorage lets compatible Windows titles stream assets more efficiently, helping reduce in-game stutter on systems that can take advantage of the feature.

The free Western Digital Dashboard for Windows allows users to monitor drive health, update firmware, and secure-erase the drive when needed, adding easy day-to-day management to the overall package.
