Yottabyte (YB)

It’s big! One yottabyte (YB) is equal to one septillion bytes. That’s 1,000,000,000,000,000,000,000,000 bytes. It’s so big that there isn’t one YB worth of computer data on the entire Web. In 2006 it was estimated at 160 exabytes. By 2009 it was 500 exabytes. When we get to 1 million exabytes, we will have 1 YB of information on the Web!
