SuperMicro - M2 and SATA Ports

castellansolutions used Ask the Experts™
Hey Guys,

Does anyone know if I on this board here: If I can use all 6 sata ports AND the M.2 drive at the same time? (Motherboard: C7H170-M)

I need to rebuild my storage box as my old trusty XEON Box finally failed on me. I want to be able to use 4x 2TB Drives and 2x 128GB SSD Drives with windows storage spaces.

All SATA posts are independent. So if motherboard has M.2 connection it has separate channel to chipset.

The answer above is correct ... but ONLY because the motherboard's M.2 slot only supports PCIe M.2 units [On board that have SATA support for the M.2 slot, using a SATA M.2 will replace support for one of the SATA ports.

So be sure the M.2 unit you buy is PCIe.
