Abstract :

Abstract: RAID is a technology that is used to increase the performance and/or reliability of data storage. The abbreviation stands for Redundant Array of Inexpensive Disks. A RAID system consists of two or more disks working in parallel. These disks can be hard discs but there is a trend to also use the technology for solid state drives. There are different RAID levels, each optimized for a specific situation. These are not standardized by an industry group or standardisation committee. This explains why companies sometimes come up with their own unique numbers and implementations. In the late 1980s, researchers at the University of California at Berkeley were looking for ways of combining disks into arrays with desirable combinations of affordability, data availability and I/O performance. In 1988, a landmark paper entitled A Case for Redundant Arrays of Inexpensive Disks was published. The paper demonstrated that arrays of low-cost personal computer disks could be effective substitutes for the high capacity, high performance disks then used with data centre computers. Five disk array models, called RAID Levels, were described.
