I have looked around here and on other sites but don't really come to a clear solution on what to do specifically with my setup.
I'm searching for a way to power the following setup efficiently:
- 1 Raspberry PI 1
- 1 Raspberry PI 3
3 Raspberry PI 3 B+
2 SEAGATE Expansion Portable (2015) 1TB
- 1 TOSHIBA Stor.E Canvio Basics black 1TB 2.5"
- 1 WD unknown 512GB
- 1 unknown 1TB
I didn't know that I need to power those HDD's externally when I bought them and now I'm therefore struggling to provide enough power for them.
I tried to connect a Y cable to a second port of the PI, which worked better for one of the drives, but it still failed when I wrote a lot of data on it.
So now I have the following ideas:
Buy 6 active power hubs USB 3.0 Power Hub, 4 USB Ports + 2.4A Charging Port, 15W(5V/3A) power adapter. Since this hub has a special port for charging, I thought it would be optimal for my problem. Attach them the following way:
Two Anker PowerPort (60W 6-Port USB Charging Hub) and a couple of USB Y cables. Connect them like this:
Is there a better way compared to those two, I want to reduce power adapter usage, don't want to use 12 since that seems a bit overkill? And if there is no better solution, which one should I use?
