RAID is the technology of grouping several physical drives in a computer into an array that one can define as one or more logical drives. Within this technology, data is stored redundantly in various ways to enhance integrity and availability. And because RAID controllers can significantly improve data transfer rates, this technology is extremely effective when implementing demanding, transaction-oriented applications. High-performance interface technology and powerful, dedicated processors allow RAID controllers to maximize throughput, plus tune a controller's performance to meet the needs of specific applications. This paper explores the basic functionality of RAID implementations, discusses the numerous RAID options available and looks at how RAID technology is poised to take advantage of new storage technologies as they emerge.
