Hi,

I understand your concern. It mainly comes down to how much earlier your
battery is drained I guess (without taking the "green" aspect into
account). Would anyone have any numbers on that? If not, we could do a
test ourselves (torturing our drives for a few hours extra,
percentage-wise the extra wear and tear is limited).

The amount of power saved will probably differ between drive
manufacturers & models as well. My gut feeling is that it won't make
that much of a difference, but it's indeed something to think about.

Greetings,

Pascal
