GreenDrive II is Fantom Drive’s answer to energy reduction and environmental responsibility by utilizing up to 40% less power without sacrificing performance.
The GreenDrive II employs variable speed disk mechanisms that increase their rotational velocity in response to host demand, resulting in virtually no performance degradation vs. a 7200RPM disk.

Additionally, no lead is used in any component of the GreenDrive II, making it Restriction of Hazardous Substances Directive (ROHS) as well as California Electronic Waste Recycling Act compliant. As a matter of fact, even the soy-based inks used to print the box are environmentally friendly.

GreenDrive yields an average drive power savings of 4-5 watts over competitors’ drives while maintaining solid performance. That power savings equates to reducing CO2 emission by up to 60 kilograms per drive per year – the equivalent of taking your car off the road for 14 days each year, and saving up to $14 per year in electricity costs depending on the power-on-hours.
