About RAID

A RAID (Redundant Array of Independent Disks) provides better
performance and reliability from combinations of drives than is
possible with the same total storage space without RAID.
This Appendix describes the various RAID levels supported by the
Adaptec Serial ATA RAID 1420SA controller.
Note: Select RAID drives of equal capacity and performance.
Otherwise, the RAID tends to be limited in capacity and
performance to that of the smallest and slowest drive.

Simple Volume

A simple volume consists of a single drive.

RAID 0

A RAID 0 is created by striping data across two or more drives.
This striping scheme creates no redundancy to protect the data.
However, because the drives share load equally, RAID 0 provides
the best read and write performance of any RAID type.
