I had a Black, and it was both noisy and vibratory. It died prematurely, to be replaced under warranty with a (non)black WD 2.5" drive that was vibratory, but quieter and still works. I also have an old Seagate 250Gb drive I keep for 'experimental' installs that sounds pretty bad. Noisiest drive I can recall was around '96-'97 where I could hear the drive movements across an office from about 20 feet away - I think it may have been made by Omega.
