G.1 Introduction
The SATA disks can be configured in a RAID array. RAID array setup is described in
Chapter 7
. The RAID array can be in one of the following configurations or levels:
RAID 0
RAID 1
RAID 10
RAID 5
JBOD
These levels are described below:
G.1.1 RAID 0 or Disk Striping
RAID 0 is a disk striping method. Data is stripped across two or more disks. RAID 0 does
not provide any redundant storage. When one of the drives fails, the data cannot be
restored. Disk striping enables faster access to the disk sectors and faster reads and
writers to and from the system.
G.1.2 RAID 1 or Disk Mirroring
RAID 1 is a disk mirroring method. Data on a first drive is copied exactly as is to a second
drive. If one of the drives fails then data is backed up on the second drive and no
information is lost. Although read and write speeds do increase, overall storage capacity is
halved. That is, if two 50 GB drives are mirrored together, the total storage capacity is
100 GB. However, since one 50 GB drive is a mirror of the other 50 GB drive, only 50 GB
of data can be stored on the system.
For disk mirroring two, four or six disks are required.
G.1.3 RAID 10 or Disk Mirroring and Striping
RAID 10 combines disk mirroring and striping. First data is mirrored on two drives (drive 1
and drive 2) and then the mirrored data is striped across two other drives (drive 3 and
