The problem is that most drives can't transfer in parallel (though I believe that, with the correct driver parameters, this particular drive can do so. I didn't comment on this because it's probably the best configuration I can think of. From a Vinum standpoint, the drives are on different controllers. Access to the Vinum volumes and the primary master drive will, of course, be impacted.
