In 1997, IBM started producing hard-disk drives that used spintronics to store data. By using spintronics, the magnetic bits can be made much smaller. The spintronics has enabled today's hard drives to store 40 times more data than was possible 8 years ago.
This 'IBM Deskstar' hard drive, made in 2001, stored 20 billion bytes. But it's already old-fashioned, today's top-of-the-range hard drives can store 8 times as much.
