Chapter 4 - RAID
The system board allows configuring RAID on Serial ATA drives. It supports RAID 0, RAID 1, and
SPAN.
X RAID Levels Explanation
RAID 0 (Striped Disk Array without Fault Tolerance)
RAID 0 uses two new identical hard disk drives to read and write data in parallel, interleaved
stacks. Data is divided into stripes and each stripe is written alternately between two disk
drives. This improves the I/O performance of the drives at different channel; however it is not
fault tolerant. A failed disk will result in data loss in the disk array.
RAID 1 (Mirroring Disk Array with Fault Tolerance)
RAID 1 copies and maintains an identical image of the data from one drive to the other drive.
If a drive fails to function, the disk array management software directs all applications to the
other drive since it contains a complete copy of the drive's data. This enhances data protection
and increases fault tolerance to the entire system. Use two new drives or an existing drive and
a new drive but the size of the new drive must be the same or larger than the existing drive.
RAID 5
RAID 5 stripes data and parity information across hard drives. It is fault tolerant and provides
better hard drive performance and more storage capacity.
RAID 10 (Mirroring and Striping)
RAID 10 is a combination of data striping and data mirroring providing the benefits of both
RAID 0 and RAID 1. Use four new drives or an existing drive and three new drives for this con-
figuration.

Description
Data striping without redundancy
Disk mirroring
Block-level data striping with
distributed parity
Combination of RAID 0 (data striping)
and RAID 1 (mirroring)
Extends capacity to the sum of total
drives, the second drive won't be used
until the first one is full.
X Setup Procedure
To enable the RAID function, the following settings are required.
1. Connect the Serial ATA drives.
2. Enable RAID in the Insyde BIOS.
3. Create a RAID volume.
3-1. Create a RAID volume if the boot type is UEFI.
4. Install the Intel Rapid Storage Technology Utility.
Step 1: Install SATA Drives
Refer to chapter 2 for details on connecting the Serial ATA drives.
Important:
1. Please make sure the SATA drives that you are to create a RAID volume with
are connected and powered, and are able to be detected by the system. Other-
wise, the RAID BIOS utility would not be accessible.
2. While creating a RAID volume, please make sure the system, drives, and cables
are perfectly steady and mounted correctly. Disturbance during creating a
RAID volume will result in irreversible data corruption sorted on the drive.
Step 2: Enter the RAID Menu in the Insyde BIOS
1. Power-on the system then press <Del> to enter the main menu of the Insyde BIOS.
2. Go to "Advanced" menu and select the "SATA Configuration" submenu.
3. Change the "SATA Mode Selection" to "RAID" mode.
4. Save the changes in the "Exit" menu.
5. Reboot the system.
