Can anyone recommend one?
I can't recommend a specific one, but any adapter card should work.
However, note that M.2 is not a single "thing" to the computer; the
drive interface can be SATA, PCI-E AHCI, or PCI-E NVMe. The first two
would look the same as a traditional SATA device to the OS, so should be
fine. The third is a different interface; I haven't looked to see if
the CentOS 7 kernel supports NVMe (I suspect it does, but you should
check before buying an NVMe device). I know that NVMe works fine with
recent Fedora.
Also note when choosing an adapter; the M.2 slot is keyed different for
the different device types, so make sure you get an adapter that matches
your device.
Thanks! I ordered a 2.5" SATA drive and they screwed up and sent me M.2
- I'll be sure to look at the booklet (Intel SSD 5 but there may be more
than one variant?)
