Well, software RAID may be faster for long, sequential writing and
reading, but we don't have very much data going in or out. Some typical
numbers may be 2-3MB/s read and ½-1 MB/s write. The parity calculation
on that is going to be negligible, no matter what solution we choose.
The problem is of course that this data is spread all over the disk, so
seek time is the major bottleneck. I do not know if the performance
hw/sw RAIDs differ significantly in this aspect. With the average RAID
card, replacing a faulty HDD is as simple and error prone as, well,
replacing a HDD when the warning e-mail drops in your inbox. I'd say
that's hard to beat as far as data security goes.

O.k., well, yesterday the other fellow yelled at me
(not really) that
I should be doing software RAID anyway. I *can* get anything overnighted
to me, to be sure. Should I?
Possibly that's the wisest thing to do here.
