Thanks for your reply! I agree about there's no sense in the backup process appearing to be "heavier" after I switched to using USB3 drives. The drive is indeed connected to a USB3 port, and directly, not via a hub.
I'll do what you suggest and make some tests. But I still find it odd that it doesn't seem to make any difference at all when I change the priority setting.
