NVMe Enterprise SSDs

Key takeaways

  • 5,526 listings match this collection right now.
  • An NVMe drive can be formatted to a 512 byte or 4K logical block size, and an array will reject a member whose format differs from the drives already in it.
  • Mixing M.2 boot modules with U.2 or U.3 data bays in one server draws on the same CPU or PCIe switch lane budget, so total NVMe capacity is capped by lanes, not bays.
  • Add-in-card NVMe drives install in a PCIe slot and skip the hot-swap bay entirely, which suits a boot or cache role but not a drive meant to be swapped live.

NVMe drives connect directly over PCIe lanes and bypass the SAS or SATA controller entirely, which is where their latency advantage comes from. In servers they appear as 2.5-inch U.2 and U.3 hot-swap drives, M.2 boot and cache modules, E1.S blades and add-in cards, and those form factors are not interchangeable.

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.
