Which M.2 SSD drive?

Not all M.2 SSD drives are equal – there are two broad stan­dards: those that con­nect us­ing the SATA-III in­ter­face, which are slower but more com­pat­i­ble, and those that use the PCI-E mod­ule. These so-called NVMe SSDs can trans­fer data up to 32Gb/s (com­pared to 6Gb/s for SATA-III), but must be sup­ported as bootable by your moth­er­board and Win­dows – of which only the later ver­sions of Win­dows 10 sup­port this fea­ture, if you want to use them at their max­i­mum speed. Don’t worry, though, as NVMe SSDs are back­wards-com­pat­i­ble and will fall back to SATA-III mode if your moth­er­board doesn’t sup­port this fea­ture.

Note, though, that these slots share re­sources with other parts of the moth­er­board, so us­ing them will dis­able at least one other port – typ­i­cally SATA – on the board. Bear this in mind when choos­ing a moth­er­board with a lim­ited num­ber of SATA ports.

If in doubt, check the spec­i­fi­ca­tions of your tar­get moth­er­board – most cur­rent-gen­er­a­tion moth­er­boards should sup­port the NVMe fea­ture (that’s ninth-gen­er­a­tion In­tel; and socket AM4 for AMD).

So-called NVMe M.2 SSD drives are sig­nif­i­cantly quicker than their SATA cousins.
