- snuxoll 5y agoNVMe is just a protocol for accessing flash memory over PCIe express, do not confuse it with the M.2 form factor (which also supports SATA and USB!). My Optane P900 I use as a ZFS log device is NVMe and plugs into a standard PCIe slot on my PowerEdge R520, and servers frequently use U.2 form factor drives.
- anarazel 5y agoNot necessarily flash - the p900 you list isn't flash for one. Nor is it necessarily over PCIe...
- walrus01 5y agoI think where people commonly confuse it is because most often when they see a M.2 device, it is the variant of the slot that exposes PCI-E pins to the NVME SSD, such as for a $100 M.2 2280 SSD from Samsung, Intel, WD, etc. As you mention there's lots of other things which can be electrically connected to a motherboard's I/O buses in a M.2 slot.
- villgax 5y agoYeah agreed, but I'm clearly not referring to the protocol.
- anarazel 5y agoE.g. U.2 drives can utilize NVMe but in a form factor easier to swap (including hot plugging support). Edit: typo
- Godel_unicode 5y agoIcy dock makes an entire range of hot-swap docks for m.2 NVMe drives.
