RAID capacity of Z170 MB's

[GeekEmeritus]

Can someone advise me if the ASrock Z170 OC Formula will permit configuration of 2 M.2 x4 SSDs along with 4 SATA 3 drives in RAID 5, a couple of DVD's and an eSATA port.

I discovered the hard way that the Gigabyte z170's disable all but 2 of the SATA ports if dual M.2's are installed

Are there any other recommendations with this storage capability? I am building a reliable high-performance workstation, not a gaming machine.

Same thing on that board you will find they all share lanes.
And the 4 Asmedia do not support raid.
4 x SATA3 6.0 Gb/s Connectors by ASMedia ASM1061, support NCQ, AHCI and Hot Plug
You will find all the Z170 boards the same way
For about the same price as the i7 6700K you could of got a better workstation processor like a 5820K.
