How big is a Petabyte, Exabyte, Zettabyte, or a Yottabyte?

This is an intuitive look at large data sizes By Julian Bunn in Globally Interconnected Object Databases.

Bytes(8 bits)

Kilobyte (1000 bytes)

Megabyte (1 000 000 bytes)

Gigabyte (1 000 000 000 bytes)

Terabyte (1 000 000 000 000 bytes)

Petabyte (1 000 000 000 000 000 bytes)

  • 1 Petabyte: 5 years of EOS data (at 46 mbps)
  • 2 Petabytes: All US academic research libraries
  • 20 Petabytes: Production of hard-disk drives in 1995
  • 200 Petabytes: All printed material OR Production of digital magnetic tape in 1995

Exabyte (1 000 000 000 000 000 000 bytes)

  • 5 Exabytes: All words ever spoken by human beings.
  • From wikipedia:
    • The world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes in 1986 to 15.8 in 1993, over 54.5 in 2000, and to 295 (optimally compressed) exabytes in 2007. This is equivalent to less than one 730-MB CD-ROM per person in 1986 (539 MB per person), roughly 4 CD-ROM per person of 1993, 12 CD-ROM per person in the year 2000, and almost 61 CD-ROM per person in 2007. Piling up the imagined 404 billion CD-ROM from 2007 would create a stack from the earth to the moon and a quarter of this distance beyond (with 1.2 mm thickness per CD).
    • The world’s technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986, 715 (optimally compressed) exabytes in 1993, 1,200 (optimally compressed) exabytes in 2000, and 1,900 in 2007.
    • According to the CSIRO, in the next decade, astronomers expect to be processing 10 petabytes of data every hour from the Square Kilometre Array (SKA) telescope.[11] The array is thus expected to generate approximately one exabyte every four days of operation. According to IBM, the new SKA telescope initiative will generate over an exabyte of data every day. IBM is designing hardware to process this information.

Zettabyte (1 000 000 000 000 000 000 000 bytes)

  • From wikipedia:
    • The world’s technological capacity to receive information through one-way broadcast networks was 0.432 zettabytes of (optimally compressed) information in 1986, 0.715 in 1993, 1.2 in 2000, and 1.9 (optimally compressed) zettabytes in 2007 (this is the informational equivalent to every person on earth receiving 174 newspapers per day).[9][10]
    • According to International Data Corporation, the total amount of global data is expected to grow to 2.7 zettabytes during 2012. This is 48% up from 2011.[11]
    • Mark Liberman calculated the storage requirements for all human speech ever spoken at 42 zettabytes if digitized as 16 kHz 16-bit audio. This was done in response to a popular expression that states "all words ever spoken by human beings" could be stored in approximately 5 exabytes of data (see exabyte for details). Liberman did "freely confess that maybe the authors [of the exabyte estimate] were thinking about text."[12]
    • Research from the University of Southern California reports that in 2007, humankind successfully sent 1.9 zettabytes of information through broadcast technology such as televisions and GPS.[13]
    • Research from the University of California, San Diego reports that in 2008, Americans consumed 3.6 zettabytes of information.
  • Internet Traffic to Reach 1.3 Zettabytes by 2016

Yottabyte (1 000 000 000 000 000 000 000 000 bytes)

Xenottabyte (1 000 000 000 000 000 000 000 000 000 bytes)

Shilentnobyte (1 000 000 000 000 000 000 000 000 000 000 bytes)

Domegemegrottebyte (1 000 000 000 000 000 000 000 000 000 000 000 bytes)

Wow theses idiots really argue about this

June 14, 2017 | Unregistered CommenterSksjejssisisis

1000 bit is 1kilobyte ,1000kilobyte is 1megabyte ,
1000megabytes is 1gigabytes, 1000gigabytes is 1 terabytes,,,,,,,, so on

Some websites are also defining this:

Brontobyte:
A Brontobyte is (you guessed it) approximately 1,000 Yottabytes. The only thing there is to say about a Brontobyte is that it is a 1 followed by 27 zeroes!

Geopbyte:
A Geopbyte is about 1000 Brontobytes! Not sure why this term was created. I’m doubting that anyone alive today will ever see a Geopbyte hard drive. One way of looking at a geopbyte is 15267 6504600 2283229 4012496 7031205 376 bytes!

According to this a xenottabyte is 1000 yottabytes. Wouldn't a brontobyte be the same thing

Can you tell me one thing 1024 Domegemegrottebytes equals how?

1 bit = 1 decision
2 bits = 2 decisions
3 bits = 3 decisions
4 bits = 4 decisions
5 bits = 5 decisions
6 bits = 6 decisions
7 bits = 7 decisions
8 bits = a letter (usually from your boss concerning your termination because all of your previous decisions were bad)

And now for something totally different ...

After we have catalog the entire universe will it require another universe to hold it? I hope String Theory pans out, that way we will have access to even more data to store and possible a dimensional data storage solution(DDSS). Already it has given us a new acronym to add to the old data banks.

I wonder if Seagate will take advantage of String Theory, once is becomes String Law, to create an inter-dimensional data storage solution to hold all this new found data? It could be called ...

Bytes are binary, nothing else. Ergo 1 byte, 2 bytes, 4 bytes, etc. Even programming languages such as Hex, etc. are based upon binary. It is the basis of all computer languages, be it hard (cards, etc.) or other. Pon or off, zero or one.
