WD_BLACK SN770 1TB WDS100T3X0E
PCIe 4.0 NVMe M.2 solid-state drive for desktops and laptops
The WD_BLACK SN770 WDS100T3X0E is a 1TB internal NVMe solid-state drive designed for desktops, laptops, and workstations with an M.2 2280 PCIe slot. It uses a PCIe 4.0 x4 interface and NVMe protocol to provide sequential read speeds up to 5,150 MB/s and sequential write speeds up to 4,900 MB/s. The drive uses 3D TLC NAND flash and has a rated endurance of up to 600 TBW. Its single-sided M.2 2280 design supports installation in systems that provide adequate clearance and PCIe Gen4 connectivity. The SN770 is also backward compatible with supported PCIe Gen3 systems, where performance is limited by the host interface.
