RAID DATA RECOVERY
RAID. Redundant Array of Independent (or Inexpensive) Disks.
 These arrays employ a combination of two or more disk drives. They are frequently used in servers for fault tolerance and performance. RAIDs are categorized by levels. RAIDs offer different fault tolerance that makes recovery of a failed drive an easy or a very complicated task. All different levels of RAID have one thing in common: they use hard drives. Hard drives will not only wear out its mechanical components in time, but will develop mechanically induced defects too.
RAID Level 0
This level provides data striping, spreading out blocks of each file across multiple disk drives, no redundancy. This improves the performance but does not deliver fault tolerance. If one drive fails, all the data will be lost, and for that reason, it can only be recommended for setting up fast systems with temporary data. RAID Level 1
This level uses disk mirroring and redundancy, providing maximum security and fault tolerance. Data can be read up to some extent, simultaneously from all drives in the array, writing, however, it performs similar to the rate of a single disk. The array can only be as big as its smallest drive. If a hard drive failed, recovery procedures are still possible.  RAID Level 3
This level provides byte-level stripping with a dedicated parity disk. Level 3 cannot service multiple request simultaneously and the fact that parity data is written to a single drive cuts down performance in writing transactions.
RAID Level 5
This level provides block-level stripping and also stripe error correction information. Good performance and security makes this level one of the most implemented RAIDs, offering good performance for all kind of applications. Each of the above levels, offer different fault tolerance that makes recovery of a failed drive an easy or a very complicated task.
