ASUS GUI RAID Manager: RAID Levels Logical Drive Block 1 Block 2 Block 3 Block 4 Block 5 Block 6 Block 7 Block 8 . . Physical Disks Mirroring Block 1 Block 2 Block 3 Block 4 . . Block 1 Block 2 Block 3 Block 4 . . In addition to the data protection RAID 1 provides, this RAID level also improves performance. In cases where multiple concurrent I/Os are occurring, these I/Os can be distributed between two disk copies thus reducing total effective data access time. RAID 1(0+1) RAID 1(0+1) combines RAID 0 and RAID 1 -- Mirroring and Disk Striping. RAID (0+1) allows multiple drive failure because of the full redundancy of the hard disk drives. If more than two hard disk drives are chosen for RAID 1, RAID (0+1) will be performed automatically. F IMPORTANT: RAID (0+1) will not appear in the list of RAID levels supported by the controller. If you wish to perform RAID 1, the controller will determine whether to perform RAID 1 or RAID (0+1). This will depend on the drive number that has been selected for the logical drive. C-4 RAID 1(0+1)
