10.1 Introduction

To support demanding disk I/O, Intel Q77/C216 chipset integrates six Serial ATA con-

trollers with software RAID 0, 1, 5, 10 capabilities.

RAID 0 striping increases the storage performance and is designed to speed up data

transfer rates for disk-intensive applications.

RAID 1 mirroring protects valuable data that might be lost in the event of a hard drive

failure.

RAID 5 array contains three or more hard drives where the data is divided into man-

ageable 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 arr ay. The p arity is striped in a rot ating

sequence to reduce bottlenecks associated with the parity calculations.

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.

10.2 SATA RAID Driver and Utility Setup

The driver is in the CD’s “07_Intel RAID_AHCI” folder. Go to the directory and follow

Intel's installation guide to install the driver and utility.

Note! For the detailed installation instructions for the SATA RAID driver and

utility, please check the User Guide in the driver CD. Path: 07_Intel

RAID_AHCI.

Note! Before you install the Intel Rapid Storage Technology, please read the

"readme.txt" which is in the folder “07_Intel RAID_AHCI”.
