What Does Pebibit Mean?
A pebibit (Pibit or Pib) is a unit of digital storage. It has a binary prefix of 250 bits or 1,125,899,906,842,624 bits, which is also equal to 1,024 tebibits (Tibit or Ti).
In 1998, the International Electrotechnical Commission (IEC) established the pebibit to clarify confusion related to the petabit, as defined by the International System of Units (SI).
Techopedia Explains Pebibit
The pebibit is still purely theoretical and not currently in use because technology has not yet evolved to the point where storage devices have the capacity to handle this level. However, if all the data in the world could be combined, the congregated value might reach the pebibit level.
