WD Black SN850X Gen4 NVMe Solid State Drive Review

Western Digital’s WD Black SN850 was one very impressive impressive drive when it came out, and honestly still to this day it is going to be one of the best performing Gen4 drives out there. Well Western Digital has recently introduced the WD Black SN850X, which comes with faster speeds, updated BiCS5 3D TLC NAND, and a new Game Mode 2.0 which is made to speed up game loading times. The advertised speeds of the 2TB version we are taking a look at today are 7300 MB/s read and 6600 MB/s write. The drive is being offered in non-heatsink and pre-installed heatsink versions and this is one of the few high performance Gen4 drives to have a 4TB version available. Let’s get it installed and see what it can do!

Special thanks to Western Digital for providing us with the WD Black SN850X Gen4 NVMe Solid State Drive to review.
