3.2 <SATA RAID Configuration>
The board integrates Intel
́
ICH9DO with RAID function for Serial ATA II drives, and
supports the configurations below:
RAID 0 (Stripping)
: Two hard drives operating as one drive for optimized data R/W
performance. It requjires two unused drives to build this operation.
RAID 1 (Mirroring)
: Copies the data from first drive to second drive for data security, and if
one drive fails, the system would access the applications to the workable drive. It needs two
unused drives or one used and one unused drive to build this operation. The second drive
must be the same or lager size than first one.
RAID 5 (striping with parity)
A RAID 5 array contains three or more hard drives where the data is divided into
manageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. The data and parity are striped
across all the hard drives in the array. The parity is striped in a rotating sequence to reduce
bottlenecks associated with the parity calculations.
RAID 10 (RAID 0+1)
A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1. The
data is striped across a two-drive array forming the RAID 0 component. Each of the drives
in the RAID 0 array is then mirrored by a RAID 1 component.
Intel Matrix Storage Technology
: This technology would allow you to use
RAID 0+1
mode
on only two drives (4 drives needed on traditional RAID 0+1). It will create two partitions on
each hard drive to simulate
RAID 0
and
RAID 1
. It also can let you modify the partition size
without re-formatted.

If you need to install an operation system on the RAID set, please use the driver disk
attached in the package when it informs you to obtain the RAID drivers.
