Frequently Asked Questions

How fast is the WD_BLACK SN770 1TB?

WD rates the 1TB model at up to 5,150 MB/s sequential read and 4,900 MB/s sequential write over PCIe Gen4. Actual speeds vary with host device, drive capacity, and usage conditions.

Will the SN770 work in a PCIe Gen3 motherboard?

Yes. WD_BLACK lists SN770 support for games developed for Microsoft DirectStorage, which is designed to cut load times by streaming assets more directly to the GPU.

What form factor is the SN770 and will it fit my build?

It is an M.2 2280 NVMe drive, the standard 80mm length used by most desktop motherboards and many laptops. Confirm your system has a free M.2 NVMe slot before ordering.
