USB 3 Hub performance when multiple USB 3 devices are connected simultaneously

Last Modified: 2015-10-16
My laptop has only 2 USB ports- 1 USB2 and 1 USB3.

I usually tether my cellphone 3G connection to USB2 port and connect 1TB External Harddisk to USB 3 port.

I saw a USB 3 hub that can connect 4, 10 or more USB3 connections at a time.

What is the effect on performance on connecting so many USB 3 gadgets to USB 3 ports.

Say i connect 3 USB 3.0 devices using a USB 3.0 hub to a USB 3.0 port on my laptop. Will i get USB 3 speeds on all the devices connected to the hub.

Will i get better 3G speed if i tether my mobile 3G to a USB 3 device connected to a USB 3 port than tethering it to a USB2 port.
