RAID configurations

If your motherboard supports Intel

Rapid Storage Technology, you can create RAID 0,

RAID 1, RAID 5 or RAID 10 congurations.

Please refer to your motherboard’s user manual for details on the actual supported RAID

congurations.

If you want to install a Windows

operating system to a hard disk drive included in a RAID

set, you have to create a RAID driver disk and load the RAID driver during OS installation.

Refer to section 1.2 Creating a RAID driver disk for details.

1.1.1 RAID definitions

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

conguration 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 5 stripes both data and parity information across three or more hard disk drives.

Among the advantages of RAID 5 conguration include better HDD performance, fault

tolerance, and higher storage capacity. The RAID 5 conguration 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.

RAID 10 is data striping and data mirroring combined without parity (redundancy data)

having to be calculated and written. With the RAID 10 conguration you get all the benets

of both RAID 0 and RAID 1 congurations. Use four new hard disk drives or use an existing

drive and three new drives for this setup.

1.1.2 Installing storage devices

The motherboard supports Serial ATA hard disk drives and PCIE SSD storage devices. For

optimal performance, install identical drives of the same model and capacity when creating

a disk array.

Refer to Chapter 2 in your motherboard’s user manual for details on installing storage

devices to your motherboard.
