Could be interesting -- but given how the freespace volume bits and
root volume map to physical space, it might mean the first drive is
going to be doing a lot of extra disk accesses if blocks are assigned
to drives in a linear fashion.  I recommend striping the blocks across
the drives to avoid hammering one drive to death (or at least the
fragile ancient media in said drive -- these drives will probably keep
working until the end of time)
