What is RAID? Why do we need it?
RAID is an acronym for Redundant Array of Independent (or Inexpensive) Disks. This method of combining several drives into one unit can offer fault tolerance and higher throughput levels than a single hard drive or group of independent hard drives.
RAID provides real-time data recovery when a hard drive fails, increasing system up-time and network availability which protecting against loss of data. Multiple drives working together also increase system performance.

RAID - IDE ?
The vast majority of RAID configurations utilize SCSI hard drives. IDE is not an ideal platform for RAID. Limitations of IDE include:
(1) data transfer rate tops out at 100 MB/s;
(2) hard drives must stay within 1.2 feet;
(3) only two drives available per IDE channel. On the othe hand, IDE could be a replacement for a Tape Backup device in a Desktop PC when using RAID Level 1 implementation (disk mirroring).
