I do not want to check the speed on a USB 3.0 flash drive or external drive. I need to know the speed of the port itself is transferring at full 3.0 capacity.
What I have is an external mechanical USB 3.0 hard drive. I know it's a 7200 rpm drive. My 3.0 USB ports on my laptop are not using the blue USB plastic to denote 3.0 speeds, they use black plastic.
Therefore I am not confidant they are running at full 3.0 speeds. I want a tool that will measure the port speeds independently of any drive or device on the USB port.
I did find this but I do not have any Advanced tab to check for or to reset the device to Super
windows - Verifying USB connection speed (USB 3 or USB 2?) - Super UserThere are four USB specs: 1.0, 1.1, 2.0, and 3.0. But to confuse things, each USB spec has more than one data rate assigned to it. Those rates are "low", "full", "high", and "super."
Therefore, benchmarking data throughput solely on speed is not necessarily conclusive as to what the actual spec being used. Thus, a USB 3.0 port may not be actually running at a "super" rating but at a "High" rating instead.
On a Windows machine, check the data rating of the USB root/hub - Goto: Device Manager --> USB Controllers --> USB Root Hub (Right Click) --> Properties --> Advanced (Tab).
It should tell you the data rating for the USB hub/port. Once you know that, you'll know the maximum throughput from the computer's POV.
Low = 1.5 Mbps Full = 12 Mbps High = 480 Mbps Super = 5 Gbps
Here is what the listing looks like in device manager Under the two 3.0 USB hubs at the top, there is no advanced tab.
