5.7. Working with RAID
RAID, or Redundant Array of Independent Disks is a storage device made up of multiple disks. A RAID, connected to a system, is shown as one logical disk unit in the operating system. RAID is a way of storing the same data at multiple places (hard disks) to improve data access, data safety, performance, fault tolerance, and to increase the mean time between failures.
Stellar Data Recovery supports data recovery from three RAID levels – RAID 0, RAID 5, and RAID 6.
RAID Reconstruction-Main User Interface screen
RAID 0 is the first level of RAID technology that uses block-level striping without parity or mirroring and has no (or zero) redundancy. RAID 0 improves performance and storage but has no fault tolerance. Any drive failure will lead to total data loss and the chances of failure increases with an increase in the number of hard disks.

RAID 5 is another level of RAID technology, which uses distributed parity and distributed data technique. This level requires at least three hard disks and a single disk failure does not lead to total data loss.
RAID Reconstruction-RAID 5 Screen
RAID 6 level uses block-level striping with double distributed parity. This level requires a minimum of four disks and it can tolerate up to two hard disk failures. This RAID level technology is intended for high-availability systems and makes larger RAID groups more practical.
