I just got a WD MyPassport external drive, that is solely powered via USB (there are no other plugs).
I have seen in various places that a powered USB port is suggested for the RPi, but I can't quite tell if that is referring to powering the Pi itself, or if you buy a powered USB strip, and plug that in to the Pi and then plug the External Drive to the power strip. And then leave the Pi itself powered by MicroUSB to the wall plug.
If I do need a powered USB, what specification do I need to look for? There are tons online, but only via amazon comments can I check if the RPi works with these -- and again there, I think people are referring to powering the Pi itself from the strip - not peripherals like HDD/Keyboard/etc. Would this work, or this Amazon one?
From what I understand, I don't need it to Backpower since I'm using the designed MicroUSB port to power the pi. Yes?
Thanks for any clarification on this!
