Simple but reliable 1

This is an adapter that case, but it is very reliable: speed worthy of the name for the USB3, I found speeds approximately 4 times higher than the USB2. I use it to run virtual machines on a laptop, an external hard drive connected with this adapter allows to have good performance.
The supplied cable USB3 is relatively short (20 cm approx) but if you work on a desktop that is not annoying.
Personally I unplug the cable of the case prompted systematically when I put it in a bag, for fear of twisting the USB3 connectivity, quite fine.
