Data Deluge

Came across this article published by MIT. Fascinating!

The amount of data we create, replicate, and store in gadgets and the cloud is growing at a staggering rate. According to IDC, the total “digital universe,” or all the digital information that has been created or replicated, grew to 1.8 zettabytes in 2011 (a zettabyte is a trillion gigabytes) in 500 quadrillion files. IDC says the total size has grown by a factor of nine over the past five years. Handily enough, in August, researchers at IBM unveiled the largest hard drive ever, capable of holding 120 petabytes (a petabyte is a million gigabytes), or about 24 billion five-megabyte mp3 songs.
