Introduction
Important
The least number of hard drives for RAID 0, RAID 1 or Matrix mode is 2.
All the information/ volumes/ pictures listed in your system might differ from
the illustrations in this appendix.
The ICH9M-E provides a hybrid solution that combines 4 independent SATAII ports for
support of up to 4 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 3Gb/s. 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 3Gb/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 ® ICH9M-E offers RAID level 0 (Striping), RAID level 1 (Mirroring and Duplexing),
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. 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.
