Setting up RAID
The motherboard comes with the Intel
®
C204 controller that supports the following SATA RAID
solution:
•
Intel Rapid Storage Technology with RAID 0, RAID 1, RAID 10, and RAID 5 support (for
Windows OS only).
RAID definitions
RAID 0
RAID 0
RAID 0
RAID 0
(Data striping)
optimizes two identical hard disk drives to read and write data in parallel,
interleaved stacks. Two hard disks perform the same work as a single drive but at a sustained data
transfer rate, double that of a single disk alone, thus improving data access and storage. Use of two
new identical hard disk drives is required for this setup.
RAID 1
RAID 1
RAID 1
RAID 1
(Data mirroring)
copies and maintains an identical image of data from one drive to a
second drive. If one drive fails, the disk array management software directs all applications to the
surviving drive as it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the entire system. Use
two new drives or use an existing drive and a new drive for this setup. The new drive must be of
the same size or larger than the existing drive.
RAID 10
RAID 10
RAID 10
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having to
be calculated and written. With the RAID 10 configuration you get all the benefits of both RAID 0
and RAID 1 configurations. Use four new hard disk drives or use an existing drive and three new
drives for this setup.
RAID 5
RAID 5
RAID 5
RAID 5 stripes both data and parity information across three or more hard disk drives. Among the
advantages of RAID 5 configuration include better HDD performance, fault tolerance, and higher
storage capacity. The RAID 5 configuration is best suited for transaction processing, relational
database applications, enterprise resource planning, and other business systems. Use a
minimum of three identical hard disk drives for this setup.
Installing hard disk drives
The motherboard supports SATA hard disk drives for RAID set configuration. For optimal
performance, install identical drives of the same model and capacity when creating a disk array.

RAID controller selection
You can choose either the Intel Rapid Storage Technology as the default utility to create RAID
set(s). See RAID configuration utility for details.
