I have a Nitro 5 (AN515-53) but I am noticing when I connect a USB 3.0 hdd to my 3.0 port on the left side of the machine, my speeds don't seem to be 3.0. I am usually averaging 80-75MB/s but always under 100MB/s.
I have all my drivers up to date, the phsyical connections are fine so I am not sure what is the issue.

and the actual drive in the case is a standard hdd
