If you bother to notice,
A lot of people on old machine may not have usb3 or 3.1 ports as you
The manufacture of the device you use didn't want to make a device exclusively for usb3
So enter why it also has esata connection options
The device is designed for usb3 usage
Your also fortunate enough to have usb3.1 as well = use it if the device likes it
Otherwise ask the manufacture of the device for the best connection
I'll bet usb 3.1 would be best
