Comparison Test: SSDs Are Not More Energy-efficient Than Traditional Hard Drives

Notebook computers, such as Apple's Macbook Air and Lenovo ThinkPad X300, can now be equipped with solid state drives. Advertisements for SSDs often claim that they are more shock-resistant, smaller in size, faster in random access speed compared to traditional hard disk drives, and also "more power-efficient than traditional hard drives." However, is the solid state drive really more power-efficient? Given that it has no motor or other parts, theoretically it should be. But the following comparative tests will surely surprise you. Because the result shows that SSDs are not more power-efficient than traditional hard disk drives.
