3.0 port question

I have 2 3.0 USB ports , I also have a usb splitter, if I plug the splitter into the 3.0 port will the speed be 3.0?
or are there 3.0 splitters for that use. Thanks

are there 3.0 splitters for that use? Yes.

To connect multiple USB 3.0 devices to a single USB 3.0 port, you will need a USB 3.0 hub, such as this example.

A USB 2.0 hub will work with a USB 3.0 port, however the outputs on the USB hub will be limited to USB 2.0.
