I want to expand my HD space to the max. If I use a USB splitter, how man hard drives can I connect to my Hopper 3? Does it work with a USB splitter on the USB 3.0 port? I'd rather not use the front USB port for aesthetic reasons. Thanks.
Use a powered USB hub. Connect as many as you like, but Hoppers will only see 2, or 3 of them at a time.
With a powered USB hub my H3's see 3 EHD's at the same time. The old Hopper UI see's 2 at a time.
