Do not mean to shoot at you either..
Though I think the majority of folks here are more or less in my predicament, from my perspective, your set up is highly outside the scope of what various equipment configs a data recovery person/company would have. They are not replying with the answers you are looking for because they do not have a good suggestion. As I grew in this community, I learned that for the most part folks here give suggestions if they have a good one. If the suggestion is not so good, they tend not to give it because of the screw up risks involved (or high cost without accomplishing their goal, so a total loss)
There are too many factors to consider in what would be the bottleneck for your aimed set up and whether it is even feasible to achieve the speeds you intend. Saying this as you have already seen in your own test from the other thread (I think it is your post) that certain technology interfaces do not necessarily meet the speeds they have been calculated and tested to deliver on their own by manufacturers or 3rd party testers. There are other intricacies that play a factor within each element within your set up as a whole. I would think here as an analogy for example the fuel mileage for a. electric car vs. hybrid vs. a diesel vs. gas. Well, who is driving the say car, what kind of driving (highway, local), is the driver an aggressive type, at what speeds, etc.
If I was in your shoes, to get as good of an idea as possible, though still not guaranteed it will achieve the results you are looking for, I would begin by breaking down the set up into separate components and collect speed specs for each (collecting info speeds for each is much more attainable from the various places, such as manufacturer, forums, your own experience, etc.) Then try to predict what the average would be. I would say reduce that average by 20% to 30% to comp for misrepresentation. Then decide if the predicted speed satisfies your expectations.
