Intel RAID

Introduction

This appendix will assist users in configuring and enabling RAID functionality and ac� celerating system on platforms

The mainboard comes with the Intel RAID controller that allows you to configure SATA hard drives as RAID sets.

Intel® RAID controller offers RAID level 0 (Striping), RAID level 1 (Mirroring and Du� plexing), RAID level 5 (Block Interleaved Distributed Parity), RAID level 10 (A Stripe of Mirrors)�.

RAID 0 breaks the data into blocks which are written to separate hard drives. Spread� ing the hard drive I/O load across independent channels greatly improves I/O perfor� mance.

RAID 1 provides data redundancy by mirroring data between the hard drives and pro� vides enhanced read performance.

RAID 5 Provides data striping at the byte level and also stripe error correction informa� tion. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.

RAID 10 Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.

Important

The least number of hard drives for RAID 0 and RAID 1 is two. The least number of hard drives for RAID 10 mode is four. And the least number of hard drives for RAID 5 mode is three.
