The WD Black SN850X is a PCIe 4.0 M.2 NVMe drive built for gaming PCs and the PlayStation 5. The 4TB version uses a WD in-house controller with TLC NAND and a DRAM cache, and it reaches sequential reads around 7,300 MB/s. Reviewers rate it among the fastest PCIe 4.0 drives for game loading, and the optional Game Mode 2.0 software adds load prediction and auto-tuning. It suits gamers and editors who want a big, fast drive without moving to PCIe 5.0, though it lacks the highest endurance ratings of some pro drives.
