RAID storage explained

RAID was originally defined as Redundant Array of Inexpensive Drives, but RAID setups were traditionally very expensive so the definition of “I” became Independent. The costs have recently come down significantly because of commoditization and RAID features are now embedded on to most higher-end motherboards. Storage RAIDs were primarily designed to improve fault tolerance, offer better performance, and easier storage management because it presents multiple hard drives as a single storage volume which simplifies storage management.
