Fascinating problem. If the dump & load programs are designed to take a
parameter for N drives for effective parallel operation, and N > 2, then
things will run a lot faster.
I can think of several ways the the data can be dumped in parallel, with
various trade-offs. Would love to know how it's implemented in practice.
