I have a 7-disk raid fibre attached and a lto3 scsi attached to my sd,
and I get the same throughput for both.  I run 10 jobs (two from each
client) to each store concurrently.  

I don't think the medium or the connection are the holdup.  My network
throughput at that time varies around 750 mbps.  I'm running postgres,
director, sd, and catalog on the internal scsi hardware raid 5 volume.  

FWIW.
