Appendix B Intel Ich7Hd Sata Raid - MSI 975X Platinum Series User Manual

Appendix B
Intel ICH7HD SATA RAID
The optional southbridge ICH7DH provides a hybrid solution
that combines four independent SATAII ports for support of up to
four Serial ATAII (Serial ATAII RAID) drives.
Serial ATAII (SATAII) is the latest generation of the ATA
interface. SATA hard drives deliver blistering transfer speeds up to
3 Gb/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 3 Gb/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 ICH7DH offers RAID level 0 (Striping), RAID level 1
(Mirroring and Duplexing), RAID level 10 (A Stripe of Mirrors) and
®
Intel Martix Storage Technology.
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. RAID 10 Not one of the
original RAID levels, multiple RAID 1 mirrors are created, and a RAID
0 stripe is created over these. 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.
The minimum number of hard drives for RAID 0, RAID 1 or Matrix
mode is 2. The minimum number of hard drives for RAID 10 mode
is 4.
All the information/volumes listed in your system might differ from
