RAID Level 1 Configuration
RAID level 1 uses a data-redundancy storage technique known as mirroring to enhance data integrity.
When data is written to the primary drive, the data is also duplicated, or mirrored, on the second drive in
the configuration.
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.
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 Computer for RAID
You can use one of two methods to configure RAID hard drive volumes. One method uses the Intel
RAID Option ROM utility and can be performed without an operating system present on the hard drive.
The second method uses the Intel Matrix Storage Manager, or Intel Matrix Storage Console, and is
performed after the operating system and the Intel Matrix Storage Console have been installed. Both
methods require that you set your computer to RAID-enabled mode before you begin.
