Results:

 As you can see the Sunbeamtech Airbox gives a respectable performance on
USB.  It blows the competition away when USB is compared to the eSATA
speeds.

The real time data transfer test using a stopwatch shows the Sunbeamtech Airbox doesn’t perform quite as well as a similar enclosure, but is far and above the better box when comparing the eSATA speeds to the USB speeds.

 Conclusion.
