ICH10R Introduction

The ICH10R provides a hybrid solution that combines 4 independent SATAII ports for
support of up to 4 Serial ATAII (Serial ATAII RAID) drives with this mainboard.
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 ICH10R offers RAID level 0 (Striping), RAID level 1 (Mirroring and Duplexing),
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. 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 5 Provides data striping at the byte level and also stripe error correction
information. 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.
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.
Intel Rapid Recover Technology utilizes RAID 1 functionality to copy data from a
designated Master drive to a designated Recovery drive. The size of the Master drive
must be less than or equal to the size of the Recovery drive. W hen a Recovery
volume is created, complete capacity of the Master drive will be used as the Master
volume. Only one Recovery Volume can exist on a system. There are 2 methods of
updating the data on the Master to the Recovery drive. They are Continuous Update
Policy and On Request Update Policy.
Important
The least number of hard drives for RAID 0, RAID 1, Recovery or Matrix
mode is 2. The least number of hard drives for RAID 10 mode is 4. And the
least number of hard drives for RAID 5 mode is 3.
