What is RAID?

Find out what RAID is.

By James Nunns

RAID, or redundant array of independent disks, is a way of storing the same data in different places.

Originally known as redundant array of inexpensive disks, it works by placing data on multiple disks so that input/output operations can overlap in a balanced way in order to improve performance.

RAID is basically a data storage virtualisation technology that combines multiple disks into a single logical unit.
