The six onboard SATA channels provided by the PCH support the following Intel Matrix
Storage Technology RAID (Redundant Array of Independent Drives) levels:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and data mirroring
• RAID 5 - distributed parity
NOTE
In order to use supported onboard RAID features, you must first enable RAID in the
BIOS. Also, during Microsoft Windows XP installation, you must press the F6 key to
install the RAID drivers. Refer to your Microsoft Windows XP documentation for more
information about installing drivers during installation. Both Microsoft Windows Vista
and Microsoft Windows 7 include the necessary RAID drivers for both AHCI and RAID
without the need to install separate RAID drivers using the F6 key.
The red eSATA connector on the back panel can be used to connect an eSATA drive.
