RAID capabilities are considered essential for most server-class computers and are widely implemented on servers. But there is no reason that RAID cannot be used on more basic PCs as well. Any computer capable of supporting more than one  hard-disk can use RAID. Why Might I Want it? RAID capabilities can provide several benefits: Redundancy  -- If one disk fails, one or more others have the same data and can  prevent data loss  until the failed drive is replaced.
