1 star deduction for the non superior data throughput. I have an average of 75MB / sec measured in continuous operation (read / write, of course, small differences, but no matter) natively on eSata makes the same HDD approximately 110MB / sec in continuous use.
And 1 Star deduction for the really incredible loose, directly seated on the board without strain relief USB3 connector. A clear case for breaking after a short time, if you take does not have a USB extension cable for strain relief.
Actually, I wanted at first the thing to return but thought that not much better enforcement, thus easily solved by short cable.
Thus, 3 stars. Since I do not really found anything better at the price, I would buy the adapter again, because it is really very low.
