I can attest to the part an excellent data rate. I do not need in life, but good to know that would be impossible.
I myself took this hub to feed multiple USB hard drives which have no external power supply. With normal, active hubs an impossible task. Either you put the plates to a free direct slot on the computer, or you take a stroke like this.
In a pinch it would work well as a normal non-powered hub, but you are allowed to connect any power-hungry USB consumers. I myself take him to play along to various songs at events and have connected three 500GB USB hard drives. Perfect work!
Highly recommended and full 5 stars.
