Hardware, Embedded Systems ACM's latest journal had an interesting article about RAID which suggested it might be time for triple parity raid. "How much longer will current RAID techniques persevere? 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."

It's also worth nothing that Accusys has a range of controllers that support triple parity RAID. Search their site for "RAID TP" for more details. q.v. http://www.accusys.com.tw/FAQDetail.aspx?Lan=en&FAQ=39

Since RAID is merely an acronym in common usage, its use in describing a product is not restricted by any standards organization. If we wanted, we could define RAID 7 here on OSnews and nobody could challenge our authenticity. However, we may need a marketing group to extol the virtues of RAID 7 and increase its global mindshare. "Our amazing disk array utilizes parity calculated from a bifurcated NAND engine to protect data segments by cross-pollinating moon beams with pixie dust." Hello, angel investors!
