I will admit that if a drive fails I will have to google for the
instructions to proceed from there. When I first set it up, I read the
info, but since I never had to use it I've completely forgotten the
specifics. And in hindsight I should have labeled the disks so I know
more easily which one failed (when one fails). Next time, I'll do it
right. :)

I have a dmcrypt on top of the (software) RAID5, so speed is not so
much of an issue in this case, but reducing physical wear & tear on
the disks would always be a good thing. Maybe someday if I am brave I
will try it... but probably not until I made a full backup, just in
case.
