I want to connect a power-hungry external drive to my Raspberry Pi 3. Normally this would mean separate external power supplies for the Pi and the external drive, or else plugging both the drive and the Pi into a powered USB hub. The first option has the disadvantage of using up two power sockets with separate wall warts; the second has the disadvantage that it requires an extra piece of equipment that takes up space and adds to the clutter on my table.
I am therefore considering an externally powered drive that features an integrated USB hub. For example, the Samsung Backup Plus Hub, which gets its power from a wall wart, has an "upstream" micro USB connector on the back and two powered USB connectors on the front. Is it possible to connect this device (or a similar one) to my Pi such that it provides both power and data? If so, do I need to run two separate cables from the drive to the Pi (one from the "upstream" micro USB port on the back and one from the standard USB port on the front)?
