ASUS P9D-M Series

5-3

The motherboards come with either an Intel

®

 C224 controller (P9D-M) or Intel

®

 C222 controller 

(P9D-MV and P9D-MX) that supports Intel

ROM Utility with RAID 0, RAID 1, RAID 10, and RAID 5 support (for Windows

®

 OS only).

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

 (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 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 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.

If you want to boot the system from a hard disk drive included in a created RAID set, copy 

the RAID driver first from the support DVD to a floppy disk before you install an operating 

system to the selected hard disk drive.
