About RAID
RAID, an acronym for Redundant Array of Independent Disks, is a technology that provides increased
storage functions and reliability through redundancy. This is achieved by combining multiple hard disk drives
into a logical unit, where data is distributed across the drives in one of several ways called RAID levels.
When a group of independent physical hard disk drives are set up to use RAID technology, they are in a
RAID array. This array distributes data across multiple hard disk drives, but the array appears to the host
server as one single storage unit. Creating and using RAID arrays provides high performance, such as the
expedited I/O performance, because several drives can be accessed simultaneously.
RAID drive groups also improve data storage reliability and fault tolerance compared with single-drive
storage systems. Data loss resulting from a drive failure can be prevented by reconstructing missing data
from the remaining drives.
The following list describes some of the most commonly used RAID levels:
