Appendix A: Intel Ich6R Sata Raid (Optional - MSI MS-9228 User Manual

Appendix A:
Intel ICH6R SATA RAID
The optional southbridge ICH6R provides a hybrid solution that combines four inde-
pendent SATA ports for support of up to four 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 combi-
nation of the two called Intel Matrix RAID Technology, which has two volume in two
hard disk.
RAID 0 breaks the data into blocks which are written to separate hard drives. Spreading
the hard drive I/O load across independent channels greatly improves I/O performance.
RAID 1 provides data redundancy by mirroring data between the hard drives and
provides enhanced read performance. Intel Matrix RAID Technology is the advanced
ability for two RAID volumes to share the combined space of two hard drives being
used in unison.
MSI Reminds You...
The maximum number of hard drives for RAID 0, RAID 1 or Matrix
mode is 2.
All the information/volumes listed in your system might differ from the
