In pioneer days they used oxen for heavy pulling, and when one ox couldn’t budge a log, they didn’t try to grow a larger ox. We shouldn’t be trying for puters, but for more systems puters.

Data!
We live in the data age. It’s not easy to measure the total volume of data stored electronically, but an IDC estimate put the size of the “digital universe” at zettabytes in 2006, and is forecasting a tenfold growth by 2011 to zettabytes. A zettabyte is 1021 bytes, or equivalently one thousand exabytes, one million petabytes, or one billion terabytes. That’s roughly the same order of magnitude as one disk drive for every person in the world.
This flood of data ing from many sources. Consider the following:
The New York Stock Exchange generates about one terabyte of new trade data per day.
Facebook hosts approximately 10 billion photos, taking up one petabyte of storage. , the genealogy site, stores around petabytes of data.
The Archive stores around 2 petabytes of data, and is growing at a rate of 20 terabytes per month.
The Large Hadron Collider near Geneva, Switzerland, will produce about 15 petabytes of data per year.
So there’s a lot of data out there. But you are probably wondering how it affects you. Most of the data is locked up in the largest web properties (like search engines), or
scientific or financial institutions, isn’t it Does the advent of “Big Data,” as it is being called, affect anizations or individuals I argue that it does. Take photos, for example. My wife’s grandfather was an avid photographer, and took photographs throughout his adult life. His entire corpus of medium format, slide, and 35mm film, when scanned in at high-resolution, occupies around 10 gigabytes. Compare this to the
