As the world focuses on being green, manufacturers are forced to cut power usage of the products they sell. Five years ago, the fastest hard drive spun at 15K RPM and created an immense amount of heat. Today, the fastest hard drive is made of solid state hardware (no moving parts), and runs drastically cooler. QEA has benefited from this trend as well, our old routers which used 750 watts/hour have been replaced with new routers only using 18 watts/hour.
