On one side of the hub with two USB 3.0 ports can be found on the front of a Gigabit Ethernet port and on the last page of a SD and TF card reader and the terminal for a power supply (micro USB connector). With the packaging is even an adapter with USB 3.0 connector and USB 3.0 Micro plug, but I could not test for lack slot.
In addition, you can still find a Quick Start Guide, a reference to the manual on the Internet and a driver CD that I did not need.
Connected to my Mac mini, the adapter will be recognized immediately, and there are all connections. The Mac mini has already a built-in SD card reader, but which is installed on the back and so this adapter is some relief. Speed-wise, I could see between two no difference. But compared to an older USB 2.0 card reader, he is faster.
As others have written, it would be nice if the adapter has a USB 3.0 port would have more, that way you only win a slot.
The Gigabit network connection I used to run my NAS in a separate network and keep out the normal Internet traffic and streaming to Apple TV there. Some relief brought the and the NAS connection has thus become a little faster.
A portable Blu-Ray burner, which is supplied with power via USB (Pioneer BDR-XD05T) did not work on the hub without additional power supply as well as two USB 2.5 boards (WD My Passport, Seagate Expansion Portable), which I have tried. That might be because the Ethernet port and SD card reader also need electricity.
All USB sticks, I've tried, but functioned without problems, even two at a time. The two ports are also so far apart that they do not get in the way.
I am very pleased with the Hub, as it everything that I want, reliably guaranteed. From the workmanship ago he differs pleasantly from other hubs of plastic.
