3.3. RAID Technology

With fast growing database applications such as World Wide Web, multimedia and so on, the data storage requirements are also growing at the same pace. Also, faster microprocessors with larger and larger primary memories are continually becoming available with the exponential growth in the performance and capacity of semiconductor devices and memories. Therefore, it is expected that secondary storage technology must also take steps to keep up in performance and reliability with processor technology to match the growth.

Development of redundant arrays of inexpensive disks (RAID) was a major advancement in secondary storage technology to achieve improved performance and reliability of storage system. Lately, the “I” in RAID ...
