Yes I have that one for an 80GB, and it is still working, that's as far as I can say as its nothing out of the ordinary, gets heated up after 2-3 hours of usage, and speed depends on your HDD.......(Just so you know, its power source is not USB, it comes with a power brick)
And please don't create multiple threads for the same question........Bump the old one, and someone will eventually answer you........
