My mobile 2.5 "USB3.0 hard disk not put into operation.
At the integrated USB2.0 ports of my Dell laptops this ran without problems.
The same applies to an older USB2.0 hard drive.
A 3.5 "USB3.0 hard drive with an external power supply, however, worked.
The transfer rate was significantly faster than that of USB2.0
Too bad, because the card completely disappears in the ExpressCard slot,
but by the lack of power supply mobile hard drives this is through liquid,
because everything else is enough and USB 2.0
