WD_BLACK SN850 1TB NVMe SSD (WDS100T1X0E) – PCIe Gen4 x4 M.2 2280, Up to 7,000MB/s

Flagship Gen4 performance for faster boots, loads and transfers.

The WD_BLACK SN850 1TB is a PCIe Gen4 x4 NVMe M.2 2280 SSD for gaming PCs and workstations. Reading at up to 7,000MB/s and writing at up to 5,300MB/s, with a 600 TBW endurance rating, it delivers fast boots, short load times and quick file transfers on modern AMD and Intel platforms.

Why Gen4 NVMe Makes a Difference for Gaming and Creation

Games and creative apps increasingly stream large assets from storage. On SATA or Gen3 drives, that means longer load screens and slower scrubbing through high-resolution footage.

The SN850 uses the full PCIe Gen4 x4 interface with WD’s in-house controller and DRAM cache. It delivers up to 7,000MB/s reads and strong random performance, so games load faster and large files open quickly.

Flagship Gen4 Performance

With up to 7,000MB/s sequential reads, the SN850 is well suited to modern gaming, 4K editing and large data transfers. It also works at Gen3 speeds in older PCIe 3.0 systems.

Game Mode and Long-Term Reliability

WD_BLACK Dashboard provides Game Mode, firmware updates and health monitoring. The drive is rated for 600 TBW and 1.75 million hours MTTF.
