M.2 SSDs

Key takeaways

  • 4,506 listings match this collection right now.
  • The module's key notch (B, M, or B+M) has to match the slot's keying, since a SATA-only M.2 slot will not carry the PCIe lanes an NVMe module needs.
  • Server boot carriers such as a BOSS card mirror two M.2 modules in RAID 1, so the pair must match in capacity and interface, not just the slot.
  • A read-intensive endurance rating suits an M.2 boot module because the operating system's write load is light compared with a data or cache tier drive.

M.2 is a board-mounted form factor, not a bay drive, and it carries either NVMe over PCIe or SATA depending on the module and the slot keying. In servers it is most often the boot device, on a carrier such as the Dell BOSS card or the HPE NS204i. Length matters: a 22110 module does not fit a 2280 slot.

How to choose solid state drives

Interface first: SATA drives work on a SAS backplane, SAS drives do not work on a SATA-only controller, and NVMe connects over PCIe lanes in U.2, U.3, M.2, E1.S or add-in-card form factors that are not interchangeable with each other. Then the endurance class the workload needs, stated as drive writes per day. Then whether the listing includes the hot-swap tray, which every listing name states.
