NVIDIA brings Redundant Array of Independent Disks (RAID) technology—which is
used by the world’s leading businesses—to the common PC desktop. This technology
uses multiple drives to either increase total disk space or to offer data protection.
RAID techniques were first published in 1988 by a multivendor consortium—the RAID
Advisory Board. RAID techniques were divided into different categories or levels.
Originally, RAID levels focused on improving resiliency or data availability. As
additional RAID levels were defined, one was introduced for improving performance. For
all levels, RAID techniques optimize storage solutions by using multiple disks grouped
together and treating them as a single storage resource.
