I've sold three or four, Merc, but never plugged one in. I can't think of any reason why they would be any different from the standard 160GB Samsung though - or, indeed, from the 80GB and 120Gb drives that are identical bar the number of heads and platters. These we have sold and used lots of, of course.
I just don't notice drive noise anymore (aside from old ones with peculiar notes - the 2.5GB Fujitsu I plugged in the other day, for example - and in any case, there are always at least 3 computers running in the workshop and the fan noise makes modern drives more-or-less inaudible. Certainly with the Samsungs, but I don't recall hearing any modern drive to speak of.
