These are interesting numbers, but I guess I would have to figure out how much time it takes to write say 500 images to calculate how much more the drive uses than the CF card. And then I'd want to know how much that number was compared to the energy required to operate the camera itself. On the surfacem there appears to be a 5 or 6 fold increase in the amount of power required, but if the power required for storing images on media is only 1% of the total power, it probably means no big difference.
