In part of our catching up with WD’s product lineup, I took a look at the WD Blue SN570. Well, last month they also introduced their newest WD Black SSD, the WD Black SN770. The SN770 slots in above the SN750 SE which came out last year and the older PCIe 3.0 SN750 and behind last year's SN850 Flagship SSD which is also from the WD Black line. It’s still weird thinking of a SN700 series drive not being the top drive but what is more interesting is the WD Black lineup expanding out with multiple gaming options in the M.2 SSD market now. Today I’m going to check out what makes the SN770 tick and check out the performance of the 1TB model that WD sent over. Let’s dive in.
