To test the WD_Black SN770M in one of our test rigs we used a Sabrent (EC-PCIE) NVMe M.2 SSD to PCIe x16/x8/x4 card – a useful, reasonably priced little adapter if you have run out of M.2 PCIe x4 slots on a motherboard as it supports 2230 / 2242 / 2260 and 2280 format drives. For more details check the Sabrent website.

For testing, the drives are all wiped and reset to factory settings by HDDerase V4. We try to use free or easily available programs and some real-world testing so you can compare our findings against your own system.
This is a good way to measure potential upgrade benefits.
