This is a common question in computing, the acronym raid (originally redundant array of inexpensive disks, now also known as redundant array of independent disks) refers to a data storage scheme using multiple hard drives to share or replicate data among the drives. Short for redundant array of inexpensive disks, raid is an assortment of hard drives connected and setup in ways to help protect or speed up the performance of a computer’s disk storage raid is commonly used on servers and high performance computers. A case for redundant arrays of inexpensive disks (raid) costs m computer systems, secondary storage must match the advances m other parts of the system a key meas . In this paper we present an extended comparative analysis, carried out by using discrete event simulation models, between two disk array architectures: the redundant arrays of inexpensive disks (raid) level 1 architecture, based on data replication and the raid level 5 architecture, based on the use of parity information.

These situations require that the traditional one hard disk per system model be set aside and a new system employed this technique is called redundant arrays of inexpensive disks or raid . Raid – redundant arrays of inexpensive disks in the 1980s, hard-disk drive capacities were limited and large drives commanded a premium price as an alternative to costly, high-capacity individual drives, storage system developers began experimenting with arrays of smaller, less expensive hard-disk drives. Raid (redundant array of independent disks, originally redundant array of inexpensive disks) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both. Disk storage prices have now decreased to the point where software redundant arrays of inexpensive disks – level 5 with eide interfaces is about a third that of disks with scsi (small .

Redundant arrays of inexpensive disks (raid), based on the magnetic disk technology developed for personal computers, offers an attractive alternative to sled, promising improvements of an order of magnitude in performance, reliability, power consumption, and scalability. Redundant arrays of inexpensive disks (raid) improves performance by expanding external storage, improving access speed, and roving reliable storage several inexpensive hard-disks are connected to one another.

Summary: the paper presents a case for redundant array of inexpensive disks (raid) as a better option over a single large expensive disk (sled) with improvements in performance, reliability, power consumption and scalability. Raid is a storage technology based acronym which stands for redundant array of independent disks or redundant array of inexpensive disks the letter “i” stands for two words, which are mentioned above but the term “independent” sounds more appropriate and is far or less subjective to it and depends on the context of the conversation.
