Power use and acoustics are listed in WD datasheets, but I guess they might not be well comparable to values from other manufacturers.

Given the fact that they lied about RPM on their datasheets, why should anyone believe other pieces of information on their datasheets are correct?

They seem to have lied elsewhere like in store pages (per other HN comments), but the datasheets specifically only mention "Performance Class" being "5400 RPM Class", which may be misleading but is not a lie IMO.

Well, I'm looking for a 19dB-class hard drive. That class spans anything between 14dB and 60dB. That's the general noise class, you know.
