Ok. thank!
Since the board is x1/2 on M.2 i wont be getting the full speeds of the 950 that is x4 . Because there is support for the Samsung SM951 M.2 drive that is x4 as well. So i am kind of lost ^_^ . What the support stands for if it wont run properly ( PCI-E 2.0 x2 is 8 Gb/s (1 GB/s) - 6.4 Gb/s (800 MB/s))?
I guess support stands for ''the system is going to detect the hardware''.
So at the end of the day its not worth going for m.2 if you are rocking an ssd raid (2.5).
