Zettabyte Defined

A zettabyte is a measure of digital storage capacity. A zettabyte is read as the 2 to the 70th power bytes. It is also equeal to a thousand exabytes, a billion terabytes or a trillion gigabytes. Simply, it would mean one billion, one terabyte hard drives would be needed to store one zettabyte of data.

Due to the zettabyte unit of measurement being so large, it is only used to measure large aggregate amounts of data. Even all the data in the world is estimated to be only a few zettabytes.

A byte is a data measurement unit that contains eight bits, or a series of eight zeros and ones. There is nine types of bytes.

  • Byte
  • Kilobyte
  • Megabyte
  • Gigabyte
  • Terrabyte
  • Petabyte
  • Exabyte
  • Zettabyte
  • Yottabyte
