Fastest sustained throughput possible from a drive array???

So basically no definitive conclusions about the feasibility
of the motherboard aspect of the proposal? In the ideal case
there would be a large set of identical slots that each have
independent bandwidth. In one article that I read they
suggested that each drive have its own slot and thus
controller card. In this case each slot would not have to be
very fast, 200 MB per second would be plenty. With 24 drives
each with 100 MB/s sustained throughput, there would be
enough extra speed to provide the minimum 1.6 GB/s for the
whole drive.

The Skulltrail seems to have a nice setup, from a bandwidth
perspective. And treats each of its large PCI Express slots
the same. At least this one is easy to analyse.

I've seen some worse motherboards. There is a Gigabyte, where
you cannot use all the PCI Express slots at the same time. One
of the slots "steals" the lanes used by the other slots.

My purpose in posting this information, is to make you aware
that sometimes there are tricks in the wiring of the
motherboards, and not everything is, as it would seem.
