Hmm.  Well, my storage is not on 9GB SSA JBOD, so whatever recommendations
I've made you can count as 'nice'.

But I don't think that your disk technology would have a huge impact on your
stgpool volume sizing.  I know my volume-size calculations are dominated by
management convenience issues.

For most backup traffic, write patterns are sufficiently chaotic that you are
more concerned with total bandwidth than some sense of streaming speed, which
is where (in my unhumble opinion) the underlying disk allocation gets really
interesting.

Would you mind expanding the acronyms?  I'd like to join the Elect.  A google
on them is not particularly conclusive.  Self-certifying filesystem?
