RAID 0
Disk Striping
RAID 0 provides the highest performance but no redundancy. Data
in the logical drive is striped (distributed) across several physical
drives.
RAID 1
Disk Mirroring
RAID 1 mirrors the
data stored in one hard drive to another. RAID 1 can only be
performed with two hard drives. If there are more than two hard
drives, RAID (0+1) will be performed automatically.
