Right, my bad. I can't edit my comment anymore but yes, it's mSATA/mPCIe (which have the same physical interface so you have to be careful which card you put in which port), not M.2. --- These interfaces can be really confusing, and it doesn't help that even manufacturers and vendors often incorrectly mix them up as well, which makes searching for adapters quite an ordeal... The Wikipedia page[0] is good as a primer now, but I remember spending like an hour or so figuring out if I could put an M.2.2260 in an M.2.2280 port (hint: the last digits only signify the length of the card so yes). And then the B-key/M-Key/E-key varieties, which ARE incompatible. I swear PCIe/SATA are worse than USB-C/TB in figuring out what you can put where to what effect...
