RAID implementation

RAID implementation improves data storage reliability and performance.
Redundant array of independent disks (RAID) is a method of configuring multiple drives in a storage

subsystem for high availability and high performance. The collection of two or more drives presents the

image of a single drive to the system. If a single device failure occurs, data can be read or regenerated

from the other drives in the array.
RAID implementation provides fault-tolerant data storage by storing the data in different places on

multiple drives. By placing data on multiple drives, I/O operations can overlap in a balanced way to

improve the basic reliability and performance of the attached storage devices.
