I have the P5W DH Deluxe from Asus. I have two SATA DVD Burners and three SATA Hard Drives. I have the OS Drive (Raptor 74) plugged into the Red connector (Beleive it's SATA1). I have the two SATA DVD burners plugged into the two black SATA connectors (Beleive they are SATA 2/3). I don't have the other two HD's connected.
I have the two Orange SATA connectors (RAID) and the other black SATA connector (Near the back of the MB). How should I connect two new hard drives (SATA 320 & 750GB's).
I'm thinking I would use the two orange connectors but don't know what I need to do in the BIOS.
