Setting Up SATA RAID or AHCI Modes
RAID
If your purchase includes the RAID (Redundant Array of Independent Disks) option,
the following pages provide an introduction to configuring your hard disks in RAID
mode. A RAID requires
two
hard disks, and you may use your hard disks in combi-
nation with Striping (RAID 0) or Mirroring (RAID 1) for either fault tolerance or
performance.
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.
RAID Level
Description
RAID 0
Identical drives reading and writing data in parallel to
increase performance
. RAID 0
implements a striped disk array and the data is broken into blocks and each block is
written to a separate disk drive.
RAID 1
Identical drives in a mirrored configuration used to
protect data
. Should a drive that is
part of a mirrored array fail, the mirrored drive (which contains identical data) will
handle all the data. When a new replacement drive is installed, data to the new drive is
rebuilt from the mirrored drive to restore fault tolerance.
