WD Red Pro are as quiet as Plus when not seeking. The seeking behaviour is something I barely notice when sitting 2 meters away from 10 spinning platters in my office. I can wholeheartedly recommend them as a size upgrade from Plus.
No problems either, but that’s just an anecdote. Worth remembering though is that review are negatively skewed since positive experiences rarely turn into a review.
They’re probably implying exactly this.
