It is very unlikely that the RAID system would ‘crash’ .. that is what it is meant for, redundancy.
We thought so too. Apparently, universal4 is right, they do crash, and even though we use hotswap HDs that didn’t help either.
Ofcourse now we have one more place to backup the data. And in case of something like that happening again, ALL data will be restored within an hour.
