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 128. 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. This method is performed after you have installed the operating system and the Intel Storage Utility. Both methods require that you set your computer to RAID-enabled mode before starting any of the RAID configuration procedures in this document. Both methods require that you set your computer to RAIDenabled mode before you begin.
