The adapter does exactly what it is supposed, 2.5 "hard drives can even be operated without power supply for drives and 3.5" hard drives you have this then connect halt. The transmission rates are very good and a real criticism I can not find so far.
Top speed, easy to use, looks stable and cables are long enough. Exactly what I was looking for.
A recommended accessories if you want to connect "naked" hard drive to your PC.
