Where did the term RAID come from?

The term RAID stands for "Redundant Array of Independent Disks." It was first coined in 1987 by researchers David Patterson, Garth Gibson, and Randy Katz at the University of California, Berkeley. The concept was developed to improve data reliability and performance by using multiple disk drives in a single logical unit. RAID systems employ various configurations to balance redundancy and speed, ultimately enhancing data storage solutions.
