I use so that my old laptop hard drive (Seagate Momentus, 7200.4, 500GB, 2.5 "), which was quite clearly heard in the laptop. Built into the housing, I could neither außergeöhnliche volume (quieter than the laptop), nor an unusual heat generation perceive. The transfer rate (USB 2.0) are absolutely unsatisfactory in Ubuntu. As only drawback processing could turn out eventually. When clean the screws a crack was heard towards the end of each, after which I then ceased to continue to rotate. That sounded definitely not good, and I (if at all) will find only in the long-term operation, or when re-up / screwing whether the problems will create. Until then, I have absolutely no complaints against this product and would recommend it unreservedly!
