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."

there are so many to choose from. ZFS is under a CDDL open source license & runs on FreeBSD, Linux, & OS X. But check the great & powerful wiki of pedia for more non-standard RAIDs & non-RAID disk arrays. the fact is that disk storage gets more complicated relative to its capacity & it doesn't matter what you use so long as it works for you & your org.
