Interesting tidbit from Mozy -- Where does all the Computer Power Go

To help you further visualize the petabyte: one petabyte is roughly one thousand terabytes, one million gigabytes, or one billion megabytes. That's the space of 10,000 laptops, each with a 100 GB hard drive, on which you could store approximately one of the following:

• 13.3 years of HD-TV video
• 10 million yards of books on a shelf
• 20 million four-drawer filing cabinets filled with text
• 250 million mp3 songs

Mozy currently stores more than 15 petabytes of customer files.
