Sata Raid Configurations - HP Xw8200 - Workstation - 1 GB RAM Technical Reference Manual

SATA Raid Configurations

This workstation supports an embedded SATA RAID. RAID (Redundant Array of Inexpensive Disks) combines
multiple physical drives together to provide either increased performance or increased redundancy.
For an embedded SATA RAID, there are two primary configurations.
RAID 0 is a striping configuration. For example, this combines two 80 GB drives into one 160 GB drive. Both
physical drives can be accessed simultaneously for better performance. This is faster than using two 80 GB
drives separately.
RAID 1 is a mirroring configuration. For example, this uses two 80 GB drives, but one drive is a complete mirror
of the other drive. The system remains functional and no data is lost if one of the drives should fail.
There are other RAID configurations, but they are not supported on an embedded SATA RAID.
