The WD Black SN770 comes in a smallish box with a clear image of the drive on the front. Under the image is the drive's capacity, the fact it's a Gen4 drive and the Sequential read performance figure (up to 5,150MB/s).

The rear of the box has a life-size image of the drive on the right-hand side while on the left is a very small English/French feature list. Between these two is a clear plastic panel through which part of the drive is visible, sitting in its protective plastic enclosure, next to which is a logo displaying the fact that the drive has a five-year warranty. The only other thing in the box is a Technical Support and Warranty Guide.

The 1TB Black SN770 is built on a single-sided M.2 2280 format. There's a lot of free space on the PCB as the major components consist of just a single BiCS5 112-layer TLC NAND package and a new 4-channel in-house controller (coded 20-82-10081-A1). WD is keeping details of the controller very close to their chest at the time of writing this review.

WD’s SSD management utility goes under the name of SSD Dashboard. With it, you can monitor drive status, performance, update firmware and monitor temperatures. There’s no cloning tool integrated into the utility but you can download Acronis True Image WD Edition from the WD website.
