RAID
The Intel ICH7R chip alows configuring RAID on Serial ATA drives. It supports
RAID 0, RAID 1, RAID 5 and RAID 0+1.
RAID Levels
RAID 0 (Striped Disk Array without Fault Tolerance)
RAID 0 uses two new identical hard disk drives to read and write data in parallel,
interleaved stacks. Data is divided into stripes and each stripe is written alter
-
nately between two disk drives. This improves the I/O performance of the drives
at different channel; however it is not fault tolerant. A failed disk will result in
data loss in the disk array.
RAID 1 (Mirroring Disk Array with Fault Tolerance)
RAID 1 copies and maintains an identical image of the data from one drive to
the other drive. If a drive fails to function, the disk array management software
directs all applications to the other drive since it contains a complete copy of the
drive’s data. This enhances data protection and increases fault tolerance to the
entire system. Use two new drives or an existing drive and a new drive but the
size of the new drive must be the same or larger than the existing drive.
RAID 5
RAID 5 stripes data and parity information across hard drives. It is fault tolerant
and provides better hard drive performance and more storage capacity.
RAID 0+1 (Mirroring and Striping)
RAID 0+1 is a combination of data striping and data mirroring without parity
having to be calculated and written. RAID 10 provides all the benefits of both
RAID 0 and RAID 1. For this setup, use four new drives or use an existing drive
and three new drives.
