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."

3. If you think ZFS is neat, I strongly recommend throwing your support behind btrfs. It's not as good as ZFS, but you will eventually be able to trust your data to it on Linux.

Is there any particular reason that btrfs isn't as good?

Last time I checked, it seemed to be a couple of missing features away from being equivalent to the first versions of ZFS.

Is it just a matter of being younger?
