Scientists create 'world's smallest hard disk' with 500x more storage space than best hard drive

Dutch scientists have created the world's smallest hard disk by manipulating chlorine atoms in order to store a kilobyte of data on a microscopic storage drive. The invention means every book ever written could be stored on an itty-bitty device. 

The team at Delft University's Kavli Institute of Nanoscience wrote 1 kilobyte (8,000 bits) of data in an area just 96 nanometers wide and 126 nanometers tall. The tiny hard disk proved to be 500 times better than the best hard drives currently on the market.  Read more.
