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. -- Chris Adams <linux at cmadams.net>
