Definitions for "Redundant array of independent disks"
A data storage method in which data, along with information used for error correction, such as parity bits, is distributed among two or more hard disk drives in order to improve performance and reliability. The hard disk array is governed by array management software and a disk controller, which handles the error correction. RAID is generally used on network servers. Several defined levels of RAID offer differing trade-offs among access speed, reliability, and cost. Windows includes three of the RAID levels: Level 0, Level 1, and Level 5.
A method of storing the same data in different places on multiple hard disks. The input/output operations can therefore overlap. RAID improves performance, increases the mean time between failure (MTBF), and increases fault tolerance.
A technology involving 2 or more hard disk s where the data is distributed based on reliability & performance.
Used to store video programming in video production and delivery environments.
