Introduction to Intel ICH6R SATA RAID
Chapter 5. Intel ICH6R RAID
Introduction
The southbridge ICH6R provides a hybrid solution that combines
two independent SATA ports for support of up to two Serial ATA (Serial ATA
RAID) drives.
Serial ATA (SATA) is the latest generation of the ATA interface. SATA
hard drives deliver blistering transfer speeds up to 150MB/sec. Serial ATA
uses long, thin cables, making it easier to connect your drive and improving
the airflow inside your PC. The most outstanding features are:
1. Supports 150 MB/s transfers with CRC error checking.
2. Supports Hot-plug-n-play feature.
3. Data handling optimizations including tagged command queuing,
elevator seek and packet chain command.
Intel ICH6R includes the RAID level 0 (striping), RAID level 1
(mirroring), and a combination of the two called Intel Matrix RAID Technology,
which has two volume in a single RAID array.
RAID 0 breaks the data into blocks which are written to separate
hard drives. Spreading the hard drive I/O load across independent chan-
nels greatly improves I/O performance. RAID 1 provides data redundancy
by mirroring data between the hard drives and provides enhanced read
performance.
