What is Pebibyte?

What is pebibyte? This question may be on the minds of many computer users who are not familiar with this term. Simply put, a pebibyte is an order of magnitude larger than a gibibyte and it’s used to measure storage space. In this blog post, we will talk about what this unit is.

A pebibyte (PiB) is a measure of storage that equals 2^50 or 1,125,899,906,842,624 bytes.

  • 1 Petabyte = 10^15 or 1,000,000,000,000,000 bytes.
  • 1 Pebibyte = 2^50 or 1,125,899,906,842,624 bytes.

Pebibytes are used to measure storage space and they’re an order of magnitude larger than a gibibyte. An important fact about these units is that the size of data written using one unit will always be identical, no matter which measurement system is used.

So if you use gigabytes or terabytes as your standard for measuring information, then regardless what you do with it in terms of compressing it and storing it on disks, all values will remain compatible when retrieved from disk because pebibytes were selected as the base unit to store data. The SI prefixes can also be applied appropriately so there’s no confusion.
