Terminology
RAID (Random Array of Inexpensive Disks) is a technology which allows the computer to see multiple drives as a single drive. Originally designed for use with mainframe computers, it is now commonly implemented on PCs to provide varying levels of redundancy. The RAID-1 definition, which is the type implemented on the Vault, is also called disk mirroring. It consists of a two-drive array in which each drive is an exact duplicate of the other. RAID-1 provides the most failsafe data protection of the various low level RAID styles.  Other RAID types are available on server class machines, with RAID-5 (using a single disk and placing the data in a particular striping order) being the most common.
