RAID Array
RAID (redundant array of independent disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement or both.
Total RAID capacity equal to the product of the drive size, the storage factor and the number of drives.
