The external HDD is an electronic device with a certain capacity and power consumption. When you select an HDD you should take into account whether it will be used at places where a permanent power supply source is available (220V socket, an external power supply unit) or at places where the battery pack of the portable computer is the only power supply source (USB or battery pack power supply).
If you chose an HDD with USB power supply you should remember that it will consume the power of the portable computer, thus the battery life will be considerably shorter during the time when the disc is used.
