M.2 SSDs

[balnazzar]

I got a few questions about new M.2 format.

1) I have a x79 mobo without m.2 slot. Using a m.2 -> pci-express 4x adaptor will involve a performance drop? The ssd will be correctly recognized by bios? Will I be albe to use it as primary boot drive?

2) If I buy an average performance model (ike crucial m550), will the m.2 format involve some performance advantage?

Thanks!
