Why use RAID?

Typically RAID is used in large file servers, transaction of application servers, where data accessibility is critical, and fault tolerance is required. Nowadays, RAID is also being used in desktop systems for CAD, multimedia editing and playback where higher transfer rates are needed. RAID Levels RAID 0: Also known as “Disk Striping”, this is technically not a RAID level since it provides no fault tolerance. Data is written in blocks across multiple drives, so one drive can be writing or reading a block while the next is seeking the next block. The advantages of striping are the higher access rate, and full utilization of the array capacity. The disadvantage is there is no fault tolerance – if one drive fails, the entire contents of the array become inaccessible.
