Data Size Matters [Infographic]
Most people understand the relative size of their digital files. That report you just saved is 318 kilobytes (kB); those vacation photos tally 750 megabytes (MB); your new iPod holds 20 gigabytes (GB) of music. When data sets start to grow, however, their sizes become more difficult to explain. How much does a terabyte (TB) hold? How many DVDs would it take to reach a zettabyte? And what on earth is a yottabyte?
Hard drive capacity has increased 50-million-fold since 1956. It took 26 years to create a 1 GB hard drive, but between 2007 and 2011, hard drives quadrupled in size from 1 TB to 4 TB. Within the next ten years, 20 TB hard drives may even become commonplace.
