WD_BLACK SN770 500GB NVMe SSD

The WD_BLACK SN770 is a consumer-grade internal SSD built for gaming and heavy workloads. It uses the M.2 2280 form factor and connects through a PCIe Gen4 x4 NVMe interface. The drive targets users who want faster load times and smoother in-game responsiveness without moving to higher-capacity models.

500GB capacity with 300 TBW endurance

At 500GB the drive holds a solid library of current titles plus patches and downloadable content. Sequential reads reach 5000 MBps and writes reach 4000 MBps, while random performance hits 460000 read IOPS and 800000 write IOPS. The 300 TBW rating and 1.75 million hour MTTF provide headroom for years of daily gaming writes before wear becomes a concern.

M.2 2280 PCIe Gen4 x4 NVMe integration

The single-sided M.2 2280 module fits standard motherboard slots and runs on the NVMe protocol with up to four lanes of PCIe Gen4 bandwidth. Active power draw is 65mW and the controller includes thermal management to sustain performance under load. The drive operates from 0 to 85 degrees Celsius and survives 1500G shock, making it suitable for both desktop and compatible laptop builds.

Questions about this item

Will the WD_BLACK SN770 work in my older motherboard that only has a PCIe Gen3 M.2 slot?

The SN770 is backwards-compatible with PCIe Gen3 motherboards; it will operate at Gen3 speeds instead of the rated PCIe Gen4 16GT/s 5000 MBps sequential read.

How can I verify the drive is delivering its rated 5000 MBps sequential read and 4000 MBps sequential write after installation?

Run a benchmark such as CrystalDiskMark on the NVMe drive; results approaching 5000 MBps read and 4000 MBps write confirm the PCIe Gen4 link is active and the SN770 is performing to spec.

Does the WDS500G3X0E retail box include a heatsink or mounting screw, or must I buy them separately?

The drive ships as a bare M.2 2280 module; any motherboard M.2 heatsink and the M.2 mounting screw are supplied by the board manufacturer, not in the SSD package.
