Bob, did your ever do further testing with the NEW Mac Pros? I have done some testing around 2 IMacs, a Mac Mini and the 2 ThunderRAIDs that I have, but due to the lack of TB ports on all these devices daisy chaining everything together is hodgepodge at best. Then if you thrown in dual monitors for the IMacs you simply run out of TB ports.
Obviously the new Mac Pro was solve a lot of the problems with lack of TB ports but from what I have read and the little testing that I have done you still deal with weird latency issues and not near the speeds that you would expect from TB.
Just wondering if the new Mac Pro acting as the hub solved (or bettered) any of the latency or speed issues?
