There's another quiet innovation within every IBM system that's contributing in a big way to reduced power consumption: disk drives. The increased capacity per drive that comes from every new generation of technology means more gigabytes per Watt - an interesting metric for the carbon footprint of information.<div>&nbsp;</div> Seagate is developing ways to go the next step and reduce the power consumed per drive, further reducing gigabytes per Watt.<div>&nbsp;</div> As the volume of data continues to mushroom, storage power consumption will become one of the key levers in the greening of IT.<div>&nbsp;</div>

Pete, thanks for the comments. I have been using "Watts per TB" with the focus to reduce this (fewer Watts is better for the environment). Certainly flipping this around to "TB per Watt" is an interesting perspective, maximizing the amount of capacity for a fixed amount of power.

If only we could scale up the performance per TB at the sametime - now wouldn't that we sweet!<div>&nbsp;</div>
