So you have the most terrible hard drive possible [1][2](they WILL ALL fail),
ran in about the most terrible RAID setup possible (only a single RAID5 would
have been worse). Now you realize why the latter was a bad idea: with such a
great number of disks, should have picked a 3x12-member RAID6 or similar. Just
let this be a lesson in component choice and risk assessment, restore from
your backups and move on.
