Overview
The 2TB SN850X is the same excellent PCIe 4.0 drive as the 1TB model, but with a higher 6,600 MB/s write speed that stays consistent even when the drive is nearly full. The 1,200 TBW endurance rating means it will last for years of heavy use. Game Mode 2.0 in the WD Dashboard software preloads game files for faster level loading - it actually makes a difference in some titles.
