The Pi 4B has 2x USB 3.0 ports. I have 2 choices to connect my hard drives:
- Using a single 10-port hub which connects to 1 USB 3.0 port.
- Using two 5-port hubs which connect to two USB 3.0 ports.
Which is better for my setup in term of bandwith? In other words, does the 2 USB 3.0 ports belong to an integrated hub and share the same root port, like the 4 USB 2.0 ports (2x USB2 + 2xUSB3 working in 2.0 mode) do?
By the way, the 10-port hub has a 12V 4A power adapter, while the 5-port hub has 5V 2A adapter (with a variation with 12V 2A available). Which one should I get? I have a total of 10 3.5" HDDs, which connected to Seagate HDD docks. That dock takes a 12V 1.5A input, but I am not sure if it provides 5V power to the HDD or relies on 5V from the USB connection.
