The foremost advantage of using a RAID drive is that it increases the performance and reliability of the system. The RAID drive is a credible example that could be used in a server. The RAID increases the parity check and thus it regularly checks for any possibility of a system crash. Disk stripping is also a hot topic when we discuss about the RAID drives. The performance is much highlighting and increases a lot when the disk stripping is done. How the performance increases a lot by the disk stripping? This is actually done by the interleaving of the bytes or the group of bytes. The interleaving of this sort is done across the multiple drives. By this procedure only one disk is reading or writing the data. The reading and writing of the data are done in a simultaneous process.
The mirroring is the complete duplication of the data. Or in the other sense the mirroring is the 100% duplication of the data on two drives. The drives may be considerably the RAID 1. The concept of parity comes after the concept and application of the mirroring. The parity involves that the data from the crashed system be matched up with the data that is stored in the other disk. The parity check is the term allotted for the work it carries out. The procedure involved is done as described below: the parity is used to calculate the data in the two drives and store the results in the third drive. In case there are more than two drives the parity check is done on all of them and the results are stored on a completely altogether different drive. The preferable device may be the RAID 3 or the RAID 5. And the failed drive is replaced.
