In my laptop ( Lenovo - y470 ) there are three usb ports and one of those is usb 3.0 others are usb 2.0 . But i don't know which one is what. Is there a way a can figure out which port is 3.0 ?
I use device manager to confirm that i have one usb 3.0 port.
When i copy data from my External HDD it transfers at 38MB/s from all of the usb ports.
