good, but rare USB cable

All perfect, except the USB connector: female USB A. So you need the provided cable which has USB A male plugs on both sides. Don't lose it, because your shop down the street certainly doesn't have that (though Digitec does).
But the SATA connector is perfectly placed. On a flat surface, it aligns with the disks' connector, so you can plug it in without risking to break the fragile SATA connector of the disk. plus
