This board has two RAID controllers. The intel are black 0, 1, 2, 3. For the install can I put the two SATA hard drives into the 0 and 1 slots in a RAID 1 configuration and the two SATA optical drives in the 2 and 3 slots, or should I use the other RAID controller for the hard disks and keep the optical disks on a separate controller?
