Are eco-friendly hard drives the next big thing for computer companies? Are they trying to save the environment, cash in on the growing buzz around eco-sensitivity or a little of both? While the jury remains out on that Western Digital, one of the most well known hard drive companies, has joined Kanguru in marketing a green hard drive for consumers and businesses.
The GreenPower Hard Drives are all internal drives which are available in capacities from 320GB to 1TB. The GreenPower Platform, as described by Western Digital, is geared towards delivering in these drives a savings of up to 40% in hard drive power consumption. Western Digital accomplishes this, it says, through several technologies. These include balancing spin speed, transfer rate and cache size; automatically unloading the heads during idle to reduce aerodynamic drag and calculating optimum seek speeds.
Western Digital says these new drives are geared towards being Energy Star 4.o compliant, meaning a trend towards minimizing a carbon footprint while realizing savings in electricity costs. WD provides, as an example, that a data center running "10,000 drives can save $100,000 in annual energy costs, and reduce CO2 emission by 600 metric tons." That would be quite an impact indeed if it proves to be true.
The first of these 1TB drives is shipping this month for the consumer My Book line of storage products. Drives for desktop computers, enterprise operations and consumer electronics devices will follow shortly thereafter.
