Western Digital SN740 256GB PCIe 4.0 x4 NVMe M.2 2280
The PCIe 4.0 x4 interface delivers up to 5150 MB/s reads and 4000 MB/s writes, with 740K random read IOPS, in a compact M.2 2280 form factor. Its low power draw and 1,750,000-hour MTBF make it a reliable choice for portable devices, though the 256GB capacity limits heavy workloads. Best for budget-conscious buyers needing a fast boot or game drive in a secondary slot, not for large-scale workstation storage.
