Idle on a GPU (in Linux) might be more when the screen is black. I don't even know how to drive my GPU hard. It's just not part of my life here.

Something like 6W idle, 8W max, etc. for my RAID Edition drives which are not WD Green drives which likely have lower numbers. Point is that there's little power saved in a box with 6 drives going from max use to idle, etc. But I know you know that! :-) Anyway, we're getting similar results is what it sounds like to me. - Mark
