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."

Forgive me for being blunt.
But you are the 2'nd man to post this link.
I'm well aware of silent corruption issues.

Never the less, if you have taken the time to read the rest of the thread before posting, you'd notice that I have fairly reasonable reasons for avoiding ZFS in production use, even though I do use Solaris.
