eBay uses 2 petabytes of storage daily and adds 10 terabytes of additional storage every week.

Think about this:

• The Library of Congress is 20 terabytes of text
• 50,000 trees worth of pages is 1 terabyte
• All the US academic research libraries is 2 petabytes

All the information in the world? I'm not entirely sure, but I have to say that this article is actually more fascinating than the one that prompted this post in the first place.

• Did you know that North American's use 11,916 sheets of paper a year (Europeans only use 7,280)?
• Also, the entire World Wide Web comprised 167 terabytes of information in 2003 (probably a bit more now, just from eBay)
• Voice telephone traffic accounts for the largest information flow in the world by a large margin over the Internet, television, and radio.
