Serial ATA (SATA)
Serial ATA (SATA) is a physical storage interface that uses a single cable with a minimum of four
wires to create a point-to-point connection between devices. It is a serial link, which supports
transfer rates up to 3Gbps. Because the serial cables used in SATA are thinner than the
traditional cables used in Parallel ATA (PATA), SATA systems have better airflow and can be
installed in smaller chassis than Parallel ATA. In addition, the cables used in PATA are limited to
a length of 40cm, while Serial ATA cables can be up to one meter in length. Overall, SATA
provides better functionality than PATA.
Introduction to Intel ICH7R Serial RAID
Located in the South Bridge of the E7230 Mukilteo chipset, the I/O Controller Hub (ICH7R)
provides the I/O subsystem with access to the rest of the system. It supports a 2-channel
UltraATA/100 Bus Master IDE controller (PATA) and four Serial ATA (SATA) ports. The ICH7R
supports the following PATA and SATA device configurations: Legacy mode and Native mode.
RAID Configurations
The following types of RAID configurations are supported:
RAID1 (Data Mirroring): an identical data image from one drive is copied to another drive. The
second drive must be the same size or larger than the first drive.
Intel Matrix Storage
The Intel Matrix Storage, supported by the ICH7R, allows the user to create RAID1 set by using
only two identical hard disk drives. The Intel Matrix Storage Technology creates two partitions on
each hard disk drive and generates a virtual RAID0 and RAID1 sets. It also allows you to change
the HDD partition size without any data.
Configuring BIOS settings for SATA RAID Functions (Native Mode)
1. Press the [Del] key during system bootup to enter the BIOS Setup Utility.
Note: If it is the
