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."

RAID is not a standard either. What does userbase have to do with anything? Same could be said about linux/BSD/windows whatever... "not everyone uses it"

You can use RAID in your solaris root partition, and then manage extra partitions and their redundancy via ZFS, and yes with triple parity even. If you are putting many TB's of data in your root partition, you deserve what you get.

What the heck do patents have to do with triple parity? I think you just had an anti-solaris narrative and decided discussing triple-parity was a good place to dump it...
