RAID Confi gurations
There are several types of RAID confi gurations (all may not be supported):
RAID 0 (Data Striping): this writes data in parallel, interleaved ("striped") sections
of two hard drives. Data transfer rate is doubled over using a single disk.
RAID1 (Data Mirroring): an identical data image from one drive is copied to another
drive. The second drive must be the same size or larger than the fi rst drive.
RAID 10 (Striping & Mirroring): RAID 0 and 1 schemes are combined (without parity
information) to get the benefi ts of both.
RAID 5: both data and parity information are striped and mirrored across three or
more hard drives.
