Western Digital SN740 latitude 5000 512GB PCIe 4.0 x4 NVMe M.2 2242
The 512GB WD SN740 delivers PCIe 4.0 x4 speeds of 5200 MB/s read and 4700 MB/s write, with TLC NAND and 380K random read IOPS, making it a fast M.2 2242 drive for compatible laptops. Its compact 22mm x 42mm form factor fits 2242 slots directly and can adapt to 2260 or 2280 with a separately purchased adapter, though it lacks portability appeal at 12.1/100. Best for budget-conscious Dell Latitude 5000 owners needing a quick internal upgrade, provided their laptop has a PCIe SSD slot and they don't require a portable external drive.
