Thank you for your tremendous help!
A few points to clarify: My card I believe is a USB 3 card.
The USB hub on which I connected the 2 TB portable drive is a USB 3 type of hub (with 7 ports on it).
The average speed that I mentioned in my previous posting about this drive was determined when copying all sorts of files ranging from a few Megabytes to the largest one being about 400 GB.
I ran USB Device Tree Viewer and the result that it gave me for the port in question was as follows.
