The M.2 drive will be either NVMe or SATA, I've never heard of one that 
does both (would add cost for no benefit over two simpler cards). The 
M.2 slot can support one or the other or both. SATA drives will have two 
notches (B+M key), NVMe is usually one (M key), but there are two-notch 
drives (B+M key) intended to be usable in M.2 slots actually intended 
for low bandwidth network cards (B key slot without SATA support). The 
M.2 keying situation is generally a bit of a mess and there's no 
guarantee that a drive that physically fits into a slot will actually 
work, while there are configurations which logically work but need a 
physical converter. I assume this is because people did things not 
originally expected by the spec to allow more flexible use of slots, but 
the result is that the keying makes things more confusing rather than 
simplifying anything.
