If a drive failure occurs, subsequent read and write operations are directed to
the surviving drive. A replacement drive can then be rebuilt using the data
from the surviving drive. Also, because data is duplicated on both drives, two
120-GB RAID level 1 drives collectively have a maximum of 120 GB on which
to store data.
NOTE: In a RAID level 1 configuration, the size of the configuration is equal to the
size of the smallest drive in the configuration.
Configuring Your Hard Drives for RAID
At some point you may want to configure your computer for RAID if you did
not select a RAID configuration when you purchased your computer. You
must have at least two hard drives installed in your computer to set up a
RAID configuration. For instructions on how to install a hard drive, see "Hard
Drives" on page 126.
You can use one of two methods to configure RAID hard drive volumes. One
method uses the Intel
®
Option ROM utility, and is performed before you
install the operating system onto the hard drive. The second method uses the
Intel Matrix Storage Manager or Intel Storage Utility, and this method is
performed after you have installed the operating system and the Intel Storage
