I found this on the Web.
M.2 slot (yielding the necessary PCI-Express 3.0 4x) into a connector for the new 2.5 SSD. While Intel ships the cable with it's 2.5 SSD, the M.2 to mini-SAS HD adapter will be known as the ASUS Hyper Kit.

How would I use this with a Raid Samsung SSD 950 Pro?

Also, the board has U.2 Connectors. Would I be able to connect a Samsung SSD 850 pro to it?
