Hard disk has a pleasing shape and is non-slippery at four small rubber feet. It works virtually silent and has in the first test data throughput (write) of measured 126MB / s at a total data size of 32GB. The included software to speed has not yet been installed, perhaps the rate is still higher. Would recommend to anyone the product. Tested on MacBook Pro with Retina display, data from SSD 09/2013 After installing the supplied software and Turbo after 1/2 year use has the value for writing speed (21860MB in 3 min) to about 121MB / s and the reading value set to 135MB / s. I'm still very satisfied.
