What Is Hardware RAID?
SearchStorage, Tuesday, December 5,2023
Hardware RAID is a form of RAID (redundant array of independent disks) where processing is done on the motherboard or a separate RAID card. With hardware RAID, logical disks are configured and mirrored outside of the storage system. A physical RAID controller manages the array, presenting data to applications and operating systems as logical units. The controller resides on a Peripheral Component Interconnect Express bus.
RAID is a technique in which data is spread across multiple hard disk or solid-state drives to improve system throughput and reduce redundancy. These drives are configured to either distribute the data load among them or to duplicate data in order to enable recovery in the event of a drive failure.
The term was first proposed in 1987 by researchers David Patterson and Randy Katz at the University of California, Berkeley. Patterson is also known for his contributions to reduced instruction set computer design and development.
