Laptop hard drives in desktop PC saves energy

Owners of PCs that consume a lot of electricity can make their computers more efficient by using a laptop hard drive. According to German technical standard certification company TUV Rheinland, the 2.5 inch models from mobile computers tend to use less power than the 3.5 inch drives. The smaller storage devices fit into desktop computers with a fitting frame.
Laptops are fundamentally more efficient than PCs with comparable performance as mobile versions of the current Intel processors use only about half as much power as the corresponding desktop model. Those who would rather use a stationary computer can get an idea of its energy consumption at the time of purchase. Expensive and speedy graphic cards for example are real energy eaters and only necessary for game players or professional graphic designers.
