What is technical Definition of RAID ?
- RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, I/O (input/output) operations can overlap in a balanced way, improving performance. Since multiple disks increases the mean time between failures , storing data redundantly also increases fault tolerance.
- Redundant array of independent disks (RAID) is a storage technology used to improve the processing capability of storage systems. This technology is designed to provide reliability in disk array systems and to take advantage of the performance gains offered by an array of multiple disks over single-disk storage.
- Raid is a method of connecting multiple drives into one logical storage unit raid partition used id ‘fd’
What is Concept of RAID?
RAID's two primary underlying concepts are:- Distributing data over multiple hard drives improves performance.
- Using multiple drives properly allows for any one drive to fail without loss of data and without system downtime.
