Western Digital WD Blue SN570

Released on October 4, 2021, the WD Blue SN570 belongs to Western Digital’s Blue NVMe family. The 1TB WDS100T3B0C uses a PCIe 3.0 x4 M.2 2280 interface with TLC NAND, rated up to 3,500 MB/s reads and 3,000 MB/s writes, and carries 600 TBW endurance.

Positioned in the budget tier, it exists to deliver affordable Gen3 NVMe responsiveness for everyday builds and upgrades. It’s a solid fit as a boot drive and game library in desktops or laptops, thanks to its single‑sided 2280 form factor and low power draw; it also works for light video‑editing scratch, though it’s not aimed at heavy sustained writes. Notable: the drive is DRAM‑less and relies on Host Memory Buffer (HMB) to map data efficiently.
