Would you say that raid-6 is suitable for storing mission-critical data, then?


What I'd say is that I don't have any evidence it's not. Unfortunately, that's not quite the same thing.


I have a .5TB raid5 array on 5 IDE disks, and given what has been said recently
about disk MTBF's and RAID failure recovery, I'm thinking it might be best to
switch to raid-6.

I guess such a switch is best implemented as {make backup, reformat, restore},
if I went ahead?

Yes, right now there is no RAID5->RAID6 conversion tool that I know of.
