I've always been afraid of the processor deciding to write garbage to the
hard drives, and the raid array dutifully accepting that garbage. I tried
hardware raid using an on-board Promise RAID controller chip back when I
was running Red Hat 9. The next version did not support the controller.
So, I just went back to sticking everything on one big drive and doing
backups to external USB hard drives. I swap back and forth between two of
them with one being off site. So, RAID prevents downtime on a drive
failure, but, in my application, seems more trouble than it's worth. At
work, though, we're working on digital cinema servers and need RAID to get
the required throughput. That's not my department, though...
