The WD Blue SN5100 is a PCIe Gen 4.0 x4 NVMe drive in the M.2 2280 form factor, sold here in a 4TB capacity. Western Digital rates it at up to 6,900 MB/s sequential read and 6,700 MB/s sequential write, with 900K random read and 1.1M random write IOPS. It sits in the budget-to-mainstream tier of Gen 4 drives, aimed at creators and professionals running large files and AI-assisted workflows. Against premium Gen 4 rivals it trades some peak speed and endurance headroom for capacity per dollar, so it suits big libraries and scratch space more than sustained heavy writes.
