What is a Pebibyte and a Exabyte?
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).
An exabyte (EB) is a unit of digital information storage equal to 1018 bytes (one quintillion bytes, or 1,000,000,000,000,000,000 bytes). It uses the standard SI decimal prefix 'exa-'. One exabyte is equivalent to 1,000 petabytes or one million terabytes.
Note: The Pebibyte is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Exabyte belongs to the imperial/US customary system.
History of the Pebibyte and Exabyte
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.
The prefix 'exa-' (representing 1018) was adopted as an SI prefix by the General Conference on Weights and Measures (CGPM) in 1975. The application of this prefix to the byte (exabyte) became necessary with the exponential growth of digital data, driven by the internet, large-scale scientific computing, big data analytics, and the expansion of cloud storage services. It represents a scale of data far beyond what was common in earlier computing eras.
Common Uses for pebibytes and exabytes
Explore the typical applications for both Pebibyte (imperial/US) and Exabyte (imperial/US) to understand their common contexts.
Common Uses for pebibytes
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.
Common Uses for exabytes
Exabytes are used to measure extremely large volumes of data storage capacity or accumulated data, typically in contexts such as:
- Total storage capacity of major cloud providers (like AWS, Google Cloud, Azure).
- Aggregate size of the entire internet or large portions of it.
- Annual global data creation estimates.
- Storage requirements for massive scientific projects (e.g., Large Hadron Collider, Square Kilometre Array).
- Capacity of national archives or vast digital libraries.
- Discussions about future data storage needs and technologies.
Frequently Asked Questions
Questions About Pebibyte (PiB)
How many bytes are in a pebibyte (PiB)?
There are exactly 250 bytes in 1 pebibyte (PiB). This equals 1,125,899,906,842,624 bytes.
How many tebibytes (TiB) are in a pebibyte (PiB)?
There are 1,024 tebibytes (TiB) in 1 pebibyte (PiB). This follows the binary prefix system where 1 PiB = 250 bytes and 1 TiB = 240 bytes, and 250 / 240 = 210 = 1,024.
What is the difference between a pebibyte (PiB) and a petabyte (PB)?
A pebibyte (PiB) represents 250 bytes (1,125,899,906,842,624 bytes), using the IEC binary prefix 'pebi-'. A petabyte (PB) typically represents 1015 bytes (1,000,000,000,000,000 bytes), using the SI decimal prefix 'peta-'. A pebibyte is approximately 12.6% larger than a petabyte (1 PiB ≈ 1.126 PB). Use PiB for precision in binary contexts (like large-scale OS reporting, HPC storage) and PB for decimal contexts (like marketing large storage systems) or when the specific definition is clarified.
What is the difference between a pebibyte (PiB) and a pebibit (Pib)?
A pebibyte (PiB) measures information in bytes, while a pebibit (Pib) measures information in bits. Assuming the standard 1 byte = 8 bits, 1 pebibyte (PiB) is equal to 8 pebibits (Pib). Both use the binary prefix 'pebi-' (250).
Why is PiB used less often than PB in marketing?
Marketing materials for large storage systems often use the decimal prefix (PB, EB) because it results in a larger-looking number for capacity compared to the binary prefix (PiB, EiB) for the same amount of physical storage. For example, 1015 bytes is marketed as 1 PB, while an OS might report a similar capacity using PiB (1 PB is approximately 0.888 PiB). Using decimal units allows manufacturers to advertise higher, rounder numbers, even though technical contexts often rely on binary measurements.
About Exabyte (EB)
How many bytes are in an exabyte?
There are 1018 (one quintillion, or 1 followed by 18 zeros) bytes in 1 exabyte (EB).
How many petabytes (PB) are in an exabyte (EB)?
There are 1,000 petabytes (PB) in 1 exabyte (EB).
How many gigabytes (GB) are in an exabyte (EB)?
There are 1,000,000,000 (one billion) gigabytes (GB) in 1 exabyte (EB).
What is the difference between an exabyte (EB) and an exbibyte (EiB)?
An exabyte (EB) uses the decimal prefix 'exa-' meaning 1018 bytes. An exbibyte (EiB) uses the binary prefix 'exbi-' meaning 260 bytes (1,152,921,504,606,846,976 bytes). An exbibyte is approximately 15% larger than an exabyte (1 EiB ≈ 1.15 EB). While binary prefixes (like GiB) are common for RAM, the distinction between EB and EiB is less frequently encountered in everyday use but is important in technical specifications requiring precision at massive scales.
