"If you've spent any amount time watching your Facebook or Twitter feed stream by, it should be obvious that the world is creating a lot of data.  But because all that data is really just a collection of ones and zeros it can be hard to actually visualize how much is really there.\nSure, we can put a number on it, like 1.8 zettabytes being created and replicated (as in copied to DVDs and shared in the cloud) this year alone \u2014 a number that doubles every two years, according to a recent study by IDC and EMC. But how much is that, really?  Not only is data itself ethereal and hard to visualize, but the numbers are so gargantuan that they quickly become too abstract to grasp.\nOne way to put it all into perspective is to hypothetically plug all that data into physical objects we all recognize.  That 1.8 zettabytes of data, for example, would require 57.5 billion 32 GB iPads to store.  How much is that?  About $34.4 trillion worth. That's equivalent to the GDP of the United States, Japan, China, Germany, France, the United Kingdom and Italy combined. And that's how much data we'll create and store just this year.\nThe infographic below contains a few more mind-blowing comparisons to help you make sense of the numbers.\n\n\n\n\nImage by Sasha McCune"^^<http://www.w3.org/2001/XMLSchema#string>
