@JustATester I don't have any knowledge of the RTL9220,from what I understand you can use the firmware tool that you showed to help you make a configuration file from I understand.
I think it was posted here before and I will try and explain it to you the way recall how to do it,please keep in mind I never had to do it.
If you open the firmware tool that you have with the enclosure plugged in and click the button that say's Dump and then a new drop down window will appear that will say Show Device Info and click on that.
You will now be looking at the Dump file which contains your enclosure's setting's as far as how long the enclosure may stay on before going to sleep if is not in use and so on.
You can copy and then paste everything that is shown there and then paste in Notepad if your using a pc and name it whatever you want with .bin at the end of it.
You may want to ask admin or someone else if what I suggested is correct.
For really good 20GBPS enclosure's I prefer Yottamaster over most because they use ASMedia controllers which I find to seem to have all the bug's ironed out them when they are released and don't often need a lot of updating.
I have this Yottamaster enclosure and the one in the second link as well,the one in the first link looks a bit like Optimus Prime from Transformers.
