Intel
RAID
Introduction
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.
