I have looked at many of the offered here USB hubs. Ultimately, I am stuck with this. The current connection and the USB cable connection is on the left (see the existing image here). I find this connection side well as the cable now running backwards and the hub thus far is on the desk. It is also so simple a USB device "just" join in this position because, as you festhällt the stroke with your right hand and "einstöpselt" left the unit. The two upper ports are good, since I often carry a USB stick back and forth and thus connect quickly.
The speed is very good. I have a large file transfer more than once on a USB key once the drive connected directly to the PC, it gave about 17.200kByte / s and the Hub about 17.100kByte / s. So about 100kB / s less. When an external HD, which was connected with two USB plugs (power supply for), I had an average speed of about 20,400 kbytes / s. At the beginning he also reached about 40MB / s, however, is then the HD cache fills up quickly and the speed drops.
