Have the dock for some time now in operation. I did not run all the time, is likely to continue to be used as external backup drive my old SATA hard disk and as it fulfills its purpose completely. Clear you can hear the hard drive and the vibrations are the dock at his desk on, but then it puts them up on some cardboard or elsewhere or come to terms with it precisely. More important to me that the write speed is acceptable and it does definitely. Just like the easily recognize the drive.
