sorry if it's sort of a dumb question....

 

when i buy a m.2 ssd with a m and b key connector (so 2 "cutouts") i can install it in a "m key" m.2 port on my motherboard and it will work fine?

 

i feel so dumb right now ^^

I would just check the if the motherboard supports either SATA or PCIE M.2 SSD's, or just one or the other.

Some motherboards have a slot that only supports PCIE, some only support SATA, some both in a particular slot.

ty for the fast reply

 

jup

1x sata + pcie (which i will need)

1x pcie only

 

so that the ssd has both cutouts for m and b does not matter?

The keys are the physical standard and from what I have seen, PCIE SSD's have the M-key and SATA drives have the B&M key. 

Those keys are only the physical standard, but the interface also matters. So if you have a SATA SSD (which I assume you have, because B&M key), it will fit in the SATA+PCIE slot of the motherboard.

The other M.2 slot is only fit for the PCIE interface.

 

A B&M key M.2 SSD has less pins than an M key M.2 SSD, so it's not like the SATA M.2 SSD is missing anything.
