In this system large number of low cost hard drives linked together to form a single large capacity storage device that gives the Excellent performance, storage capacity and more reliability over old storage solutions. RAID is implemented with three primary reasons: Redundancy, Increased performance, Lower costs. Where Redundancy is the most valuable factor in the development of RAID for Server environments .In the event of failure RAID is helpful in the form of backup of the data in storage array. The method of redundancy depends on the version of RAID Used. It was widely used for storage in the Enterprise and server markets but now it also used by end user system. Besides the basic Common RAID configuration the different combinations of duplex/ Mirror Stripping (with or without parity )or combination of these can make up the Different RAID levels or Version Of RAID ranging From RAID 0 to RAID 10. Each version of RAID Level varies from each other in Features and techniques used :Some of them widely used Are RAID 0,RAID1,RAID5 and RAID 10 RAID 0: It is the Simplest RAID level and involves no redundancy, Stripping technique of without parity is used ,It is mostly popular among the Lower end of Market Place due to its Cost and overall best Performance characteristics of single RAID level .It requires minimum of two hard disk, Its storage capacity is 100% if identical drives are used .Its Fault tolerance is none . Its availability is lowest of any RAID level , and Random Read /Write performance and Sequential Read/ Write performance is satisfactory and up to the level. The cost of RAID 0 is lowest from all level of RAID. Its use is recommended on non critical data , (or data that changes infrequently and is backed up regularly) requiring high speed, particularly write speed, and low cost of implementation. Audio and video streaming and editing; web servers; graphic design; high-end gaming or hobbyist systems; temporary or "scratch" disks on larger machines. RAID 5 : It stripes both data and parity information across three or more drives. Any how RAID 5 is most popular among all the RAID Level. It provides data striping at the byte level,It also gives correct error information ,resulting good performance and fault Tolerance. In a RAID 5 Fault tolerance is uphold by ensuring that the parity information for any given block of data is placed on a drive separate from those used to store the data itself. Performance will depend to some extent upon the stripe size chosen. It requires minimum of three hard disks. Due to its high capacity ,good storage efficiency and performance along with moderate cost it is considered as an Ideal and best suited for transaction processing mostly , used for general purpose service along with relational Database applications, planning of firm resources and other systems.RAID 5 is most popular execution of RAID. RAID 10 RAID 10 is a stripe of a mirror ,It provides data mirroring from one Data disk manager to another ,RAID 10 gives faster data read/ write performance as compared to RAID 5 as it does not require to manage parity. However with half of the drive in the group used for data and other half used to mirror ,RAID 10 disk groups have less capacity than RAID 5 disk groups. But along with RAID Server Utility there are number of unforeseen events will cause the RAID Server Failure ,In such disaster, the normal operations of company will come to a halt. Due to short specialized Data recovery, Failure of any drive results in loss of all data. Following are the reasons where Data recovery company Recover the Data From RAID Server Failure.
