There’s a new report out from research firm IDC that attempts to count up all the zeroes and ones that fly around our digital world. I remember reading about the last such report, from the University of California, Berkeley. That report found that 5 exabytes of data were created in 2003. The new IDC report says the number for 2006 is 161 exabytes! Why the difference?
[The Berkeley researchers] also counted non-electronic information, such as analog radio broadcasts or printed office memos, and tallied how much space that would consume if digitized. And they examined original data only, not all the times things got copied.
In comparison, the IDC numbers ballooned with the inclusion of content as it was created and as it was reproduced – for example, as a digital TV file was made and every time it landed on a screen. If IDC tracked original data only, its result would have been 40 exabytes.
Even still, that’s an incredible increase in just three years. Apparently we don’t even have enough space to store all that data:
IDC estimates that the world had 185 exabytes of storage available last year and will have 601 exabytes in 2010. But the amount of stuff generated is expected to jump from 161 exabytes last year to 988 exabytes (closing in on 1 zettabyte) in 2010.
Pretty hardcore, huh? You can read about zettabytes at Wikipedia. I’m not too worried about not having enough space though, even if we were attempting to store all that data (which we aren’t). Hard drives are already approaching the terabyte mark, so who knows how big they’ll be in 2010. Then of course there’s also the ever falling costs of DVD-like media.
More importantly, I bet a lot of the storage we “have available” right now is totally underutilized. You’d be hard pressed to find a computer that comes with less than 80 GB of storage these days, and I can assure you there are plenty of users who never even come close to filling it up. Heck, even I am only using about 75% of the storage I have available on my computer (420 GB out of 570 GB) and I bet a lot of it could be deleted (I’m a digital pack rat).
