The petabyte is a multiple of the unit byte for digital information. The prefix peta indicates the fifth power of 1000 and means 1015 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes or 1000 terabyte, or 1 000 000 gigabytes . The unit symbol for the petabyte is PB.

The zettabit is a multiple of the unit bit for digital information or computer storage. The prefix zetta (symbol Z) is defined in the International System of Units (SI) as a multiplier of 1021 (1 sextillion, short scale),[1]and therefore 1 zettabit = 1021 bits = 1 000 000 000 000 000 000 000 bits = 1000 exabits. The zettabit has the unit symbol Zbit or Zb.
