Yottabyte

What is a Yottabyte and what are the ratios between Bit and Yottabyte?

Smartpedia: A yottabyte – also known as a yotabyte or yByte – is the largest unit of quantity in computer science. A yottabyte corresponds to 1 208 925 819 614 629 174 706 176 bytes.

Yottabyte – the largest unit of quantity in information technology

A yottabyte is a quantity of information technology for storage capacities or data volumes. The smallest electronic storage unit is a bit. It contains binary information – 0 or 1 – and therefore means “binary digit”. The largest digital storage unit¹ is a yottabyte – also known as a yotabyte, yobibyte, ybyte or yb.

What are the proportions between bit and yottabyte?

  • 8 bits – eight binary information – are one byte.
  • 1024 bytes are one kilobyte (KB, KBbyte).
  • 1024 kilobytes are one megabyte (MB, MByte).
  • 1024 megabytes are one gigabyte (GB, GByte).
  • 1024 gigabytes are one terabyte (TB, TByte).
  • 1024 terabytes are one petabyte (PB, PByte).
  • 1024 petabytes are an exabyte (EB, EByte).
  • 1024 exabytes are a zettabyte (ZB, ZByte).
  • 1024 zettabytes are a yottabyte (YB, YByte, Yobibyte).

For simplicity’s sake, manufacturers and professional articles use a conversion in steps of 1,000, so that 1,000 bytes represent one kilobyte and 1,000 kilobytes represent one megabyte. For a yottabyte, this would result in a deviation of more than 20%:

  • 1 yb = 1 000 000 000 000 000 000 000 000 bytes = 1024 bytes (with rounding)
  • 1 yb = 1 208 925 819 614 629 174 706 176 bytes = 280 bytes = 10248 bytes

The long road to the yottabyte

Commercial hard disks in laptops and desktop computers are now in the terabyte range. The data volume per month for mobile phone contracts is often in the single-digit gigabyte range. In 2000, total Internet traffic was around 2.4 petabytes, and in 2018 the monthly volume was an estimated 97,500 petabytes per month. Videos are responsible for most Internet traffic, so it is assumed that the streaming platform Netflix alone is responsible for approx. 15% of all Internet traffic. It is estimated that the worldwide data volume in the Internet will amount to approximately 192,000 petabytes per month.
