What comes after Petabyte? It is a Tape Drive (not)

What is an Exabyte? When I saw this title on a post at one of my favorite blogs, SP360 that VoIP IP Telephony connects to, although I first had the exabyte tapedrive in my mind, I brain was already questioning what Cisco or SP360 got to do with a tape drive. After reading the article What is an Exabyte? and then the follow up, now I know that;
Cisco's global IP Traffic Growth study is forecasting 29 exabytes of IP Traffic per month or nearly 350 exabytes per year by 2011.

At Home, the story is video, video, video. Here are some video’s effects as a driver of bandwidth growth.

• Three years from now, Internet video will be six times what it is today, and twenty times what it was in 2006.
• In 2011, online video will generate 1 billion DVDs worth of traffic each month.
• Online video will drive 30% of consumer Internet traffic by 2011.

At Work, new business services and applications will drive the growth:
• By 2010, telepresence will generate more traffic than the entire US Internet backbone in 2000.

On the Move: the coming ubiquity of Mobile Data
• Mobile data traffic in 2011 will be sixteen times what it is today.

I already knew that an exabyte (derived from the SI prefix exa-) is a unit of information or computer storage equal to one quintillion bytes. It is commonly abbreviated EB. When used with byte multiples, the SI prefix may indicate a power of either 1000 or 1024, so the exact number may be either:

* 1,000,000,000,000,000,000 bytes — 1000,⁶ , or 10¹⁸, or
* 1,152,921,504,606,846,976 bytes — 1024⁶, or 2⁶⁰.
Here is a little table;
