Have installed as additional data plate the WD80000AARS. Also under Windows 7 you must first apply the WD Alignment Tool (Approximately 3 hours), so that the sector size is set at 4K. Then the plate is also quite fast (average transfer rate 80 MB / sec .; without proper alignment when writing slowly (about 30 MB / sec.)). In any case, it is very quiet and does not generate any annoying vibrations.
