right now I'm transferring 4TB of files from HDD1 to HDD2 both connected to the same dual bay usb 3.0 docking station (specifically this one). The file manager of my pc says "approx. 9 hours left".
It happens I have two identical dual bay usb 3.0 docking station. Would it be faster if I connect HDD1 to dock1 and HDD2 to dock2, and connect the two docks to two different usb3.0 ports?
