The movie Avatar takes up over one petabyte of storage space.

A petabyte is the equivalent of 500 hard drives, each with a capacity of 2 terrabytes (a terrabyte to 1,000 gigabytes!). That’s the size of a 32 YEAR long mp3 file!!

The movie was shot in 3-D and rendered in one of the most powerful data centers in the world. Its computing core adds up to 40,000 processors and 104 terabytes of RAM. It would be realistic to assume that a significant portion of the film's $300 million budget went to storage space.

You can’t scroll through a Microsoft Excel spreadsheet forever.

Yes, folks, there is a limit to even what Excel can do. In the old version of Excel, you can only scroll over as far as column IV and you can only scroll down as far as row 65536. As of the 2007 version you can go as far as column XFD and row 1048576. If you need to fill up any more cells after that, you'll have to use "Sheet 2".
