I am about to setup my Raspberry Pi 2 as a plex server and wish to connect the old HDDs I have knocking around.
I want to use a powered hub as I know the Pi itself won't be able to power lots of HDDs. My idea is also that the hub powers the Pi itself via one USB port out of the hub and into the micro USB power port on the Pi.
I'm under the impression that the Pi 2 is safe being backfed, so that shouldn't be an issue, but my main concern is power.
I'm looking at two diff 7 port hubs,
one is known to work well, whereas I can find no comment about the anker one, (although from my experience, anker are one of the top manufacturers out there).
My concern is, will I be able to power up to 6 HDDs from the 2A hub (1 port will be used to power the Pi) or will I run out of power, and therefore should I pump out for the more powerful one?
I'm aware that the Pi 2 can't transmit at USB3 speeds, so that part will unfortunately be lost/wasted.
