One can get that hardware resillience by copying the kernel onto a
floppy for an alternative if the first hard disk fails.  (Cost is
5 minutes plus $1 for a floppy plus $30 for a floppy drive.)

When some hardware RAID controllers fail, you lose ALL data.  It happened
to a friend's Linux system at work.  This was a disaster as they were not
doing backups 'cause they had RAID.  This problem would not have happened
with software RAID.
