USB 3.0 Hub copying between external drives

[OspreyO]

If you have a powered USB 3.0 hub and you've USB 3.0 drives externals attached to it. But the PC/laptop is USB 2.0. If you copy files between the drives will it be at USB 3.0 or USB 2.0 speeds?

The controller would be on the hd pcb and i assume the hub.

I don't have a 3.0 hub to try

Pity.

Does FW or Thunderbolt work the same?

Just out of curiosity.
