Simple, fast, effective ... honors!

Serious seller: fast shipping (same day) and produces consistent with the description.
In confronting the issue, USB3 is also compatible on your conventional USB 2.0 ports, it will just go slower (in theory).
Rates measured core i7 with 32GB of RAM, internal SSD External SSD (256GB Samsung 840 Pro): 165Mo / s
with e-SATA dock: 265MO / S, I can only assume that this case saturates to 165Mo / s (one large file).

It's still a very comfortable speed, 5s for a 700MB file, 35secondes about for a 4.5Go file

The hard disk (classic or SSD) is easily inserted, no screws and no tools are required.
The case of the cover slips to come firmly to lock. This is handy, because you can easily change disk and put in the needed when needed.

The finish is very good, however, the call premium is a bit exaggerated.
The product comes in a beautiful package that will remind Apple accessories, with a small notive and USB 3.0 cable (standard to all external USB3.0 hard drives).

An LED indicates power to the box via USB, and it changes color losqu'il there was trade between the computer and the box.

What could be improved: providing a rubber shell that would protect the casing from impacts.
This would be a fairly low surout but a good guarantee of our dear data.
