Redundant Array of Independent Disks. A set of physical disks that are act as a single physical volume and use parity checking to protect against disk failure.
A new type of hard disk composed of more than one hundred 5.25-inch disks with a controller mounted in a single box.
Acronym for redundant arrays of independent disks. This phrase was introduced by David Patterson, Garth Gibson, and Randy Katz at the University of California at Berkeley in 1987. The goal of RAID is to use multiple small, inexpensive disk drives to provide high storage capacity and performance while maintaining or improving the reliability of the disk subsystem. Patterson, Gibson, and Katz described five different methods, which are known as RAID levels 1 through 5. Each level uses one or more extra drives to provide a means of recovering data lost when a disk fails, so that the effective failure rate of the whole disk subsystem becomes very low. Recently, Katz has defined a sixth method, RAID 6, which improves reliability even further, and a configuration that provides no data recovery has popularly become known as RAID 0.
Redundent Array of Inexpensive Disks. In networking and truly critical applications, a method of using several hard disk drives in an array to provide fault-tolerance in the event that one or more drives fail catastrophically. The different levels of RAID,0 through 5, are each designed for a specific use; there is no difference in speed or quality between these levels. The correct level of RAID for your installation depends on how you use your network.
Set of redundancy standards for disk subsystems (RAID 0-6), developed by the University of Berkeley and adopted by the RAID Advisory Board. RAID is set to be superseded by a more up-to-date set of standards (FRDS, FTDS, and DTDS). See also RAID 0, RAID 1, RAID 2, RAID 3, RAID 4, RAID 5, RAID 6, RAID 7.
Redundant Array of Independent Drives -- These types of arrays duplicate the data on redundant disk drives, so a failure in one disk still allows access to the remaining disk drive drive and its data, allowing for a high data availability. If one disk crashes, the data can be pulled from another disk without re-booting the system.
Redundant Arrays of Inexpensive Disks. This disk subsystem architecture uses multiple hard drives to write data to achieving redundancy and enhancing fault resilence. Instead of buying huge, monolithic drives (SLEDs), you combine multiple smaller drives to save money, increase performance, and increase reliability. In practice however, RAID systems cost more and are not as fast as the SLEDs they replace. There are several types of RAID schemes; each one is numbered. (7/96)
(redundant arrays of independent/inexpensive disks) RAID is an assembly of disk drives, known as a disk array, that operates as one storage unit. In general, the drives could be any storage system with random data access, such as magnetic hard drives, optical storage, magnetic tapes, etc. When the speed (data transfer rate) is an issue, the fastest SCSI hard drives are typically used. For details go here.

It refers to the practice of storing data on several drives so as to improve performance and increase fault tolerance. A RAID drive system appears to the operating system as a solitary logical hard drive. RAID technology uses the striping technique, partitioning each drive's storage space into units ranging from 512 bytes to several Megs. These strips are interleaved and addressed in order.
A form of fault tolerance. RAID 0 (no fault tolerance) uses data striping to distribute data evenly across all physical disks in the array, but has no redundant data. RAID 1+0 (drive mirroring) duplicates data from one drive onto a second drive. RAID 5 (distributed data guarding) distributes parity data across all drives in the array, and uses the parity data and data on remaining drives to reconstruct data from a failed drive. RAID ADG (advanced data guarding) is similar to RAID 5, but uses two independent sets of parity data. Refer to Appendix D for more details.

Duplicates data on one drive to another so that if one crashes, the system keeps running. RAID are relatively affordable today. • Redundant Power Supply Converts the power from the wall into power suitable for the computer's components. Power supplies are subject to failure. In every "Mission Critical" server we sell it goes with a second (or even a third) power supply, hence "redundant."
Redundant Arrays of Independent Disks RAID has revolutionized the way on-line data is stored in computers. Spanning the entire spectrum from personal computers to super computers, RAID technology offers significant improvements in reliability, availability and serviceability. The RAID acronym first appeared in 1988 in the earliest of the Berkeley Papers written by Patterson, Gibson & Katz of the University of California at Berkeley. The RAID Advisory Board has since substituted Independent for Inexpensive. A series of papers written by the original three authors and others defined and categorized several data protection and mapping models for disk arrays. Some of the models described in these papers, such as mirroring, were known at the time, others were new. The word levels used by the authors to differentiate the models from each other may suggest that a higher numbered RAID model is uniformly superior to a lower numbered one. This is not the case.
A storage method that uses several small hard disks in parallel to do the job of a larger disk.
A method of writing data simultaneously over multiple disk drives in disk arrays as if they were one physical unit for increased data protection.
A method of combining multiple disk drives into a single logical storage unit. Multiple levels of RAID provide different features. RAID Level 0 is the fastest type of RAID. It stores data across all the drives, letting users access information from multiple drives simultaneously. RAID Level 1 protects data by mirroring it on multiple drives, so performance is only slightly better than that of a single drive. RAID Level 5 does a combination of the two, providing the best overall balance.

Data is stored on multiple magnetic or optical disk drives to increase output performance and storage capacities and to provide varying degrees of redundancy and fault tolerance. Instead of storing valuable data on a single hard disk that could fail at any time, RAID makes sure a backup copy of all information always exists by spreading data among multiple hard disks.

RAID refers to a drive architecture designed to safeguard critical data through redundancy. In theory, RAID arrays composed of conventional discs can function for hundreds or even thousands of years without losing data because of a disc failure. RAID also offers other benefits: it can improve input/output performance, make servicing simpler and quicker and allow users to fine-tune the drive system to match the needs of specific applications. The following standard RAID specifications will be used here

( edundant rray of ndependent isks) is a way of storing same data in different places on many hard drives. By using this method, the data is stored redundantly, also the multiple hard drives will appear as a single drive to the operating system. RAID level 0 is known as striping, where data is striped (or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID level 1 is known as mirroring, which stores the data within at least two hard drives, but does not stripe. RAID level 1 also allows for faster access time and fault-tolerance, since either hard drive can be read at the same time. RAID level 0+1 is both striping and mirroring, providing fault-tolerance, striping, and faster access all at the same time. [ more on RAID

Redundant Array of Independent Disks (sometimes called Redundant Array of Inexpensive Disks). RAID is comprised of either IDE or SCSI hard disks where each HDD stores a replica of data stored on its neighboring drive. One of the obvious advantages is data preservation: if one disk is to fail there's always another that contains exactly same data. Another advantage of RAID is improved data access (retrieval) speed.

Redundant Array of Inexpensive Disks - a method of combining several relatively cheap (e.g., SCSI-2) disks into a single unit where the disks operate in parallel to give higher throughput. Thus, data may be striped across the disks so playback or recording runs at the sum of the transfer speeds of the disks. Some levels allow for hot spares so that extra disks keep error correction data that allows one of the disks to be replaced in case of failure while the array keeps running.
Redundant Array of Independent Disks - a method used to standardize and categorize fault-tolerant disk systems. RAID levels provide various mixes of performance, reliability, and cost. Three of the the most implemented RAID levels are Level 0 (striping), Level 1 (mirroring), and Level 5 (RAID-5). RAID disk systems may offer advantages during video capture.
Redundant Array of Independent Disks (RAID) is a technology that uses multiple physical disks to enhance I/O performance, data redundancy, or both, transparent to the host operating system. Common RAID levels are listed below. Simple or concatenation: Data is written linearly across a collection of disks. RAID-0: Striping, but no redundancy. Data is written across multiple disks simultaneously, in stripes, for improved performance. RAID-1: Mirroring, for the purpose of redundancy, by maintaining two or more copies of every block of data on separate physical disks. If one disk fails, the information can still be accessed. RAID-5: Striping with parity, requiring a minimum of three disks. The parity data is stored within the stripes, and is used to apply data correction for data recovery. RAID-0+1: Mirroring a striped RAID (stripe disks, then mirror the stripes). RAID-1+0: Striped array of mirroring (mirror disks, then stripe on top of the mirrors). Provides a greater degree of reliability than RAID-0+1.

RAID is an acronym for redundant array of independent disks. RAID configurations are most commonly used in servers, however PC users are starting to take advantage of them too. A RAID configuration consists of two or more hard drives recognized by the operating system as a single hard drive. When the user makes a request to "save" data, it is saved to all hard drives, thereby automatically making a back up. In addition, data can be read from both hard drives simultaneously, improving performance. However, there are more than 10 types of RAID, some which vary from this definition.

Where two or more drives are used in tandem to protect data and improve performance.
Redundant array of inexpensive disks. Alternate meanings include redundant array of independent disks and redundant array of inexpensive devices.
RAID stands for Redundant Array of Independant(or Inexpensive) Disks. This is a technology of using multiple hard drives to achieve redundancy, or to achieve higher speeds. It has many uses in the computer world, but is also used in Digital video recording.
RAID stands for Redundant Array of Independent Disks. Several different forms of RAID implementation have been defined. Each form is usually referred to as a "RAID level."
A hard disk array that either increases the speed of disk input-output or mirrors the data for redundancy, or provides both of these features. Users may access the RAID as if it were one drive, although it may be divided into multiple partitions.
RAID is an acronym for redundant array of independent disks. A RAID uses an array of disks that are independent from one another to store the same data in several places. The primary objective of a RAID is to back up important data in a manner that is safe from potential problems like hard drive failures.
In computing, the acronym RAID (originally redundant array of inexpensive disks, 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. Depending on the configuration of the RAID (typically referred to as the RAID level), the benefit of RAID is to increase data integrity, fault-tolerance, throughput or capacity, compared with single drives. In its original implementations, its key advantage was the ability to combine multiple low-cost devices using older technology into an array that offered greater capacity, reliability, speed, or a combination of these things, than was affordably available in a single device using the newest technology.
