M.2 NVMe SSD

NVMe drives in the M.2 form factor, PCIe 4.0 and 5.0, from Samsung, Lexar, Kingston and others. Any current board takes a PCIe 4.0 drive; a 5.0 drive needs a 5.0 slot to run at full speed and usually a heatsink, which some boards supply. For most desktops the capacity matters more than the last few hundred megabytes a second.
