Many people say the sure way to distinguish an M.2 SATA SSD from an M.2 NVME SSD is the card edge key. SATA=B+M key while NVMe=M ksy.
I don't think so. There are M.2 NVMe SSDs with B+M keyed card edge!
Has anyone ever seen one?
Thanks for your reply. The WD Blue SN500 NVMe SSD is an excellent example of refutation of the claim that ALL NVMe SSDs are M only Keyed.There's plenty of B+M NVMe drives, they're limited to x2 lanes. Anything Phison E8/E8T-based, the WD SN500 (SanDisk controller), SX6000 (original, Realtek controller), NM500/520 (Marvell controller), etc.
See my edit and the reply from Maxxify.so you said said one. what the make and model?
