[SOLVED] M.2 types M vs M+B

[david.goullioud]

I am getting a motherboard with a M.2 (M key) slot and I want to use an ssd on it. Should I use an M key or an M+B key ssd? What is the difference?

There is no real difference, it's just how to motherboard accepts the ssd. If the motherboard is a M key, then it makes no difference whether you get m+b or just m, but if the motherboard is m+b, you can only get m+b ssd
