Summary: I use this with my macbook pro and macbook air and I absolutely love it! I frequently transfer from my laptop to my local server and it actually will transfer at gigabit speeds! I have mine always plugged into a USB 3.0 hub as kind of a make shift docking station and it works great! Even over the hub it easily transfers data at full gigabit speeds!
Summary: With the exception that the Startech needs a driver to run, it is about perfect in its operation. have never had an issue with it and once it's installed it works fast and continuously. Very pleased with these. Have purchased 2 now, both for use on Macs - one in a home network, one in a corporate Windows network.
Summary: After reading reviews on other sites, I downloaded and installed the newest drivers before it arrived since the driver disk has old versions. Once it was here, I plugged it in and it was recognized immediately. It works great and frees up the Thunderbolt port on my Macbook Air!
