RAID, short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance improvement. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers. RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall performance which offers superior read/write performance, storage capacity and reliability over older storage solutions. There are different RAID levels and RAID 0, RAID 1, RAID 5 are the most common used.
