1.2 zettabytes of data created in 2010 - Blog
For the last five years or so, IDC has released an EMC-sponsored study on "The Digital Universe" that looks at how much data is created and replicated around the world. When I last blogged about it back in 2008, the number stood at 281 exabytes per year. Now the latest report is out, and for the first time the amount of data created has surpassed 1 zettabyte! About 1.2 zettabytes were created and replicated in 2010 (that's 1.2 trillion gigabytes), and IDC predicts that number will grow to 1.8 zettabytes this year. The amount of data is more than doubling every two years! Here's what the growth looks like: How much data is that? Wikipedia has some good answers: exabyte, zettabyte. EMC has also provided some examples to help make sense of the number. 1.8 zettabytes is equivalent in sheer volume to: Every person in Canada tweeting three tweets per minute for 242,976 years nonstop Every person in the world having over 215 million high-resolution MRI scans per day Over 200 billion HD
