You can disable the aggressive parking behavior ("Intellipark") with WD's own wdidle3.exe [1] or idle3-tools [2]. Disabling Intellipark was literally the first thing I did with each of the three WD Green drives I've owned since 2011 (got two but one failed early on and was replaced), so I can't really compare their performance with this setting on and off; however, I can say that I haven't noticed the drives being parked more aggressively than similar Samsung or Seagate drives. I used the official wdidle3.exe under FreeDOS for each drive. [1] http://support.wdc.com/product/download.asp?groupid=609&sid=113 http://support.wdc.com/product/download.asp?groupid=609&sid=... [2] http://idle3-tools.sourceforge.net/ http://idle3-tools.sourceforge.net/ Edit: changed "aggressive spin-down behavior" to "aggressive parking behavior". It actually isn't quite clear how disabling Intellipark affects disk spin-down behavior. Edit 2: There's also wdantiparkd (http://www.sagaforce.com/sound/wdantiparkd/ http://www.sagaforce.com/sound/wdantiparkd/). I have not used it but it might help you if tuning the drive itself doesn't work.
