7.9.3 RAID1 system (optional)
This is a RAID1 system configuration (mirroring with two hard disks). This configuration
enhances system availability as the system is able to continue operation if a hard drive fails,
or if there is a cable problem at a channel.
The two hard disks are configured as follows in the factory state of the device:
RAID1 system
Partition C: System, NTFS, 25 GB
Partition D: Data, NTFS, remaining capacity
Note
You can find information regarding Intel RAID controllers in the RAID documentation on the
included "Documentation and Drivers" CD in the Drivers\RAID\Intel directory.
