WD_BLACK SN850X 1TB NVMe SSD

The WD_BLACK SN850X is a 1TB internal solid state drive built for gamers and power users who need fast load times and responsive storage. It uses PCI-Express 4.0 x4 with NVMe protocol and 3D NAND TLC memory backed by 1GB of DRAM cache.

M.2 2280 PCIe 4.0 integration

The drive fits a standard M.2 2280 slot on desktop or laptop motherboards that support PCIe 4.0, delivering up to 7300 MB/s sequential read and 6300 MB/s sequential write. No separate heatsink is included, so the host system must provide adequate airflow or an aftermarket cooler.

Thermal and endurance profile

Operating temperature range spans 0°C to 85°C with Adaptive Thermal Management to throttle under heavy load. The drive is rated for 600TB written and 1.75 million hours MTTF, while random performance reaches 800000 IOPS read and 1100000 IOPS write.
