What is a Pebibyte?

Definition

A pebibyte (PiB) is a unit of digital information storage equal to 250 bytes, which is exactly 1,125,899,906,842,624 bytes (or 10245 bytes). It uses the binary prefix 'pebi-' established by the International Electrotechnical Commission (IEC). The pebibyte was created to provide an unambiguous measurement for byte multiples based on powers of 2, distinguishing it from the petabyte (PB), which is based on the decimal prefix 'peta-' (1015 or 1,000,000,000,000,000 bytes).

History

The prefix 'pebi-' (representing 250) was defined by the IEC in 1998 alongside other binary prefixes (kibi-, mebi-, gibi-, tebi-, exbi-). Before this standard, the SI prefix 'peta-' (P) was ambiguously used to represent both 1,000,000,000,000,000 (1015, as per its SI definition) and 1,125,899,906,842,624 (250) in computing contexts, especially for very large data volumes. This led to significant confusion when comparing storage capacities advertised by manufacturers (often using decimal prefixes) and those reported by operating systems or used in technical specifications (often using binary interpretations). The introduction of the pebibyte (PiB) aimed to resolve this ambiguity by providing a specific term for 250 bytes.

Common Uses

Pebibytes are used in contexts dealing with extremely large amounts of data storage where precision based on powers of 2 is necessary:

  • Measuring the capacity of very large-scale storage systems, data centers, and cloud storage infrastructure.
  • Reporting file system sizes and disk space usage by operating systems for extremely large volumes, especially where IEC standards are followed.
  • High-performance computing (HPC), large dataset analysis (Big Data), scientific research, and simulations involving massive data storage requirements.
  • Technical specifications for enterprise-level storage hardware and software where exact binary multiples are crucial.
  • Archiving and backup systems handling petabyte-scale data.
