The RAID levels were codified in the late 1980s; double-parity RAID, known as RAID-6, is the current standard for high-availability, space-efficient storage. The incredible growth of hard-drive capacities, however, could impose serious limitations on the reliability even of RAID-6 systems. Recent trends in hard drives show that triple-parity RAID must soon become pervasive. In 2005,\n            <jats:italic>Scientific American<\/jats:italic>\n            reported on Kryder\u2019s law, which predicts that hard-drive density will double annually.
