Here are some fascinating stats about data storage (thanks to my friend Glenn Rempe for finding some), spawned in part by my purchase of an Infrant ReadyNAS NV+ 3TB device:
From an article in Computer Technology Review:
In terms of raw numbers, IDC, a leading market intelligence and research firm, estimates the volume of digital data in the world at 2.81 exabytes (EB), or 2.81 million terabytes (TB) as of 2007*. It’s a volume, IDC notes, that is larger than the number of stars in the universe. More astoundingly, IDC also estimates that the amount of digital data will grow by a factor of 10 every five years, thereby surpassing the number of atoms in the universe in about 15 years.
You could store video of your entire life in a petabyte. 1 petabyte is about 2,000,000 hours of video based on current video file size. And there are 700,000 hours in an 80 year old person’s life.
Finally, here’s a link to an article from Wired called “The Petabyte Age: Because More Isn’t Just More – More is Different.” Staggeringly, Google, processes a petabyte of data every 72 minutes.
