Motherboard: ASUS Crosshair with nForce 590 SLI AMD chipset, and SATA Drives: 2 Hitachi Deskstar 500GB with data on both (one is the boot drive), 2 1TB Hitachi Deskstars with data on neither. I want data redundancy. What is the best configuration with my number of drives, two RAID 1 setups, or RAID 0+1? And how do I set it up, especially with existing data? Can I just move the data from my secondary 500GB to one of the 1TB drives and do the setup, or do i need to move the data completely and do a clean OS install?
