ASSIGNMENT - 6 Tejaswi Abbu
RAID (Originally Redundant Array of Inexpensive Disks), Now commonly (Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both.
Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the required level of redundancy and performance.

RAID 0:-
RAID 0 comprises of striping, without reflecting or equality. The limit of a RAID 0 volume is the entirety of the limits of the circles in the set, the same as with a spread over volume. There is no included excess for taking care of …show more content…

In this manner, any read solicitation can be overhauled by any drive in the set. On the off chance that a solicitation is telecast to each drive in the set, it can be adjusted by the drive that gets to the information first, enhancing execution. Supported read throughput, if the controller or programming is improved for it, approaches the entirety of throughputs of each drive in the set, generally with respect to RAID 0. Real read throughput of most RAID 1 executions is slower than the quickest drive. Compose throughput is constantly slower in light of the fact that each drive must be upgraded, and the slowest drive restrains the compose execution. The exhibit keeps on working the length of no less than one drive is functioning.

RAID 2:-
RAID 2 comprises of bit-level striping with committed Hamming-code equality. All plate shaft revolution is synchronized and information is striped such that each successive piece is on an alternate drive. Hamming-code equality is figured crosswise over relating bits and put away on no less than one equality drive.This level is of authentic hugeness just; in spite of the fact that it was utilized on some early machines (for instance, the Thinking Machines CM-2).

RAID 3:-
RAID 3 comprises of byte-level striping with devoted equality. All circle axle turn is synchronized and information is striped such that each successive byte is
