Western Digital BLACK SN770M 500GB M.2 2230 NVMe PCIe Gen4 x4 Internal SSD

The Western Digital WDS500G3X0G-00CHY0 is a solid state drive that uses the NVMe protocol and belongs to the BLACK SN770M family. It slips into the compact M.2 2230 slot and provides 500GB of rapid, reliable storage for games, applications, and media without adding bulk.

The drive communicates through a PCIe Gen4 x4 interface, giving data room to move fast enough to keep load screens short and installs quick. Western Digital pairs that bandwidth with nCache 4.0, a dynamic SLC cache that absorbs write bursts so large game files and project assets copy smoothly.

Support for Microsoft DirectStorage lets compatible Windows games feed textures straight from the SSD to the GPU, which helps open worlds and complex scenes appear almost instantly. Whether you play on a Steam Deck, race on an ASUS ROG Ally, or work on a Surface Laptop or slim Dell notebook, the SN770M keeps the system responsive.

The 500GB of TLC 3D NAND balances speed with endurance while drawing little power, a trait that extends battery life in handheld consoles and travel-ready laptops. With no moving parts, the drive resists bumps and vibrations during daily commutes.

Installation is straightforward: remove the device back panel, slide the SN770M into the 2230 slot, secure the screw, and power up. In just a few minutes you have extra space for more titles, larger media libraries, or additional virtual machines without relying on external drives.
