The Western Digital WD Blue SN5000 4TB is an M.2 2280 PCIe Gen 4 NVMe SSD for compatible PCs, suited to creators and power users who want ample project storage and sequential read speeds up to 5,500 MB/s.
Recommended For
- PC users expanding a game library or everyday app storage who want 4TB in a PCIe 4.0 M.2 drive; a review found good everyday performance, while the large capacity suits keeping more games and files installed.
- Laptop owners with a compatible M.2 2280 NVMe slot who want a high-capacity upgrade: the 4TB drive has a thin, single-sided design, and a review found it stayed relatively cool during testing.
- Creators who store project files and make occasional large transfers, rather than constant multi-terabyte writes; testing found strong performance in a 450GB write, with speeds slowing after the drive’s cache fills during a much longer write.
