Disappointing.
Positives:
The case itself makes a good impression. Although it is made of plastic, but that is dearer to me than a cheap aluminum housing. The SSD is secure in it and does not wobble. Well, that a full USB 3.0 port was blocked and no microUSB 3.0 port (which can easily break).
Because of the performance not achieved I can not forgive more than 1 star.
EDIT:
The thing is more complicated than I thought. In summary:
1. powered on LogiLink USB 3.0 Hub: USB 2.0 speed (bad).
2. directly connected to the Surface Pro 2: USB 3.0 speed (music files with about 170MB / s copied) (good!).
3. on non-powered Dell U3014 Display USB 3.0 Hub: USB 3.0 speed (good interesting surprise!).
4. connect the desktop to the housing port (Via chip likely): USB 2.0 speed (bad).
As you can see is not the same as USB 3.0 USB 3.0.
On controllers connected correct it is working. Disappointing is all, which is why I now forgive 2 stars.
