Setting Up SATA RAID or AHCI Mode
AHCI Mode
Advanced Host Controller Interface (AHCI) is an interface specification that allows
the storage driver to enable advanced serial ATA features such as Native Command
Queuing (for maximum hard disk efficiency and performance). AHCI mode can be
supported by one or two hard disks. Make sure you install the Intel® Rapid Storage
Technology application if you have set up your hard disk(s) in AHCI mode (see
“Intel Rapid Storage Technology” on page 7 - 9)
RAID
To configure your RAID (Redundant Array of Independent Disks) system in Strip-
ing (RAID 0), Mirroring (RAID 1) or Recovery modes (see Table 7 - 1, on page 7 -
3) you will require at least two identical (see sidebar) hard disks. Note that if you
are using Advanced format hard disks that have a 4KB physical sector size, and
you are installing a Windows 7 release pre Service Pack 1, you will need to install
a driver from the Device Drivers & Utilities + User’s Manual disc at OS installation
(see page 8 - 21).
Intel® Rapid Storage Technology Application
Make sure you install the Intel® Rapid Storage Technology application if you
have set up your hard disk(s) in RAID mode (see “Intel Rapid Storage Technolo-
gy” on page 7 - 9).
