Zumastor would not speed up a single snapshot. It solves the problem of
supporting multiple (as in lots of) snapsnots with the same performance
as a single snapshot (so that taking a snap every 5mins becomes
practical). BTW, rewriting that 1G file would be normal speed, since
the modified chunks have already been copied to the snapshot.
