gloTermRAID

Redundant Array of Independent Disks (RAID) is a technique that server-class computers use to both improve speed of on-disk storage and to improve reliability. Using multiple disks, the computer splits up and/or copies data across the disks so that if one of the disks breaks, no data is lost and the server doesn't crash. You will often hear storage described as RAID 0, RAID 1, etc. The number indicates the type of storage, not the number of hard drives.
