Connected to a USB 3.0 port on my laptop and just tested with - Ethernet, - two USB 3.0 portable drives (A and B), - one wireless USB receiver Logitech. The copy speed from A to the laptop reached about 107 MB/s, similar to when A was directly connected to the laptop. The copy speed from A to B (A->Notebook->B) reached about 90MB/s, similar to connecting B to laptop directly and copying from laptop to B. Copying B to laptop and A to laptop at the same time , reached about 200MB/s, which means the hub can handle two USB 3.0 ports at full speed! Ethernet just plugged in and played. The only problem I found was with my Logitech wireless receiver. The connected mouse pointer was sluggish and jerky during the simultaneous data transfer test, and then continued to behave erratically. The pointer behavior only recovered when I unplugged and plugged the receiver back in.
