more crappy = ca exist

good, well the USB 2 already, have to sit on it, the interface that connects to USB1, even on a USB port so it will take a maximum of 2 to settle for 12 Mbit / sec network throughput
Then, the drivers are so unstable OMG ... from a NAS sends stable over 80 mb / sec this key does not allow constant rates ...
ca freezes under Win7 network transfers
Mac, no drivers to work, and I'm not the last nozzle for drivers ...

Overall I recommend to everyone, it is waste of time and money and energy ...
return to sender, erk

by cons nothing to say about the book that Amazon still as fast (5 Stars)
