Raw drives, we have an enclosure, generously donated by Bytemark. (The
backup server is donated by Thomas Krenn in Germany, if my memory serves
me right).

There are practical problems with your suggestions, such as resizing the
RAID taking a very long time when we add a new disk (you're looking at
weeks of seriously reduced performance).
So far, there's been little interest in hacking on the software driving
snapshot.debian.org by anybody but weasel. If people start showing up
with patches that make it consume less space: great, but I'm not going
to hold my breath.
