RAID stands for Redundant Array of Independent Disks, and was originally a technology that allowed computer users to achieve mainframe-class storage reliability from low-cost and less reliable PC-class disk-drive components by means of a technique of arranging the devices into arrays for redundancy. RAID is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives.

When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. Intratec Date Recovery is able to use the proper recovery protocols that are essential to prevent data loss or damage to file system structures.
