About Petabyte (PB)
A petabyte (PB) equals 10¹⁵ bytes (1,000 terabytes) in the SI decimal system. Petabytes describe the storage scale of large enterprises, government data archives, and hyperscale cloud data centers. A single large data center can hold multiple petabytes; the NSA's Utah Data Center is estimated to store yottabytes. Major internet companies accumulate petabyte-scale data daily. The petabyte sits at the boundary between what individual organisations manage (petabytes) and what only the largest global infrastructure handles (exabytes and above).
All photos shared on Facebook in a day amount to roughly 1–2 PB. The Human Genome Project produced about 200 PB of genomic data. The Library of Congress holds an estimated 10–20 PB of digital content.
About Exbibit (Eib)
An exbibit (Eibit) equals exactly 2⁶⁰ bits (1,152,921,504,606,846,976 bits) in the IEC binary system. It is approximately 15.29% larger than the decimal exabit (10¹⁸ bits). The exbibit sits at the top of currently practical IEC binary bit units for data storage and network specifications. It corresponds to exactly 128 PiB (pebibytes). At this scale, the 15.3% gap between SI and IEC units represents over 170 petabits of absolute difference per unit — the most practically significant discrepancy in the SI/IEC comparison for bit-based units.
The theoretical maximum aggregate bandwidth of a planned exascale supercomputer's storage fabric may be expressed in exbibits per second in academic design papers.
Petabyte – Frequently Asked Questions
How many terabytes are in a petabyte?
1 petabyte (PB) = 1,000 terabytes (TB) in the SI decimal system. In the binary IEC system, 1 pebibyte (PiB) = 1,024 tebibytes (TiB) = 1,125,899,906,842,624 bytes. The distinction matters for enterprise storage procurement: a petabyte of raw disk capacity appears as about 909 TiB in an OS reporting binary units.
What organisations actually store petabytes of data?
Petabyte-scale storage is common at: social media platforms (Facebook/Meta stores over 100 PB of photos alone), streaming services (Netflix's content library is estimated at 100+ PB), government agencies (US NSA, CERN particle physics data), genomic research institutions, and large financial exchanges storing tick-level trading data. Major cloud providers (AWS, Azure, GCP) collectively store zettabytes.
How much does a petabyte of storage cost?
In 2024, cloud storage costs roughly $20–25 per TB per month (S3 standard tier), making 1 PB approximately $20,000–$25,000/month. Raw enterprise disk hardware for 1 PB runs about $20,000–$50,000 upfront (at $20–50 per TB for high-density drives), plus ongoing power, cooling, and management overhead. Tape-based archival storage is considerably cheaper at $2–5 per TB.
How much data does YouTube receive per day?
YouTube users upload approximately 500 hours of video per minute, or 720,000 hours per day. At an average compressed size of 1–2 GB per hour of HD video, that equates to roughly 720–1,440 TB (0.7–1.4 PB) of new video data per day — before YouTube re-encodes into multiple formats and quality levels, which multiplies storage requirements several-fold.
What is beyond a petabyte?
The SI prefix hierarchy above petabyte: exabyte (EB, 10¹⁸ bytes), zettabyte (ZB, 10²¹ bytes), yottabyte (YB, 10²⁴ bytes), ronnabyte (RB, 10²⁷ bytes), and quettabyte (QB, 10³⁰ bytes) — the last two added by the BIPM in 2022. Current global data storage is estimated in the hundreds of exabytes; no single organisation approaches yottabyte scale.
Exbibit – Frequently Asked Questions
What is the difference between exabit and exbibit?
An exabit (Ebit) = 10¹⁸ bits (SI decimal). An exbibit (Eibit) = 2⁶⁰ bits ≈ 1.1529 × 10¹⁸ bits (IEC binary). Exbibit is 15.29% larger — the cumulative product of using 1,024 instead of 1,000 at each of six prefix steps. This is the largest practically relevant SI vs IEC gap for bit units in current storage contexts.
Does anyone actually use exbibits?
Exbibit is used in: computer science academic literature on exascale computing, theoretical storage system design papers, and formal IEC/IEEE standards. No commercial product, OS, or consumer application currently displays exbibits. It is primarily a unit for academic and standards consistency — ensuring the IEC prefix family extends uniformly from kibi- to exbi- (and beyond to zebi- and yobi-).
What comes after exbibit in the IEC binary system?
After exbibit (Eibit, 2⁶⁰ bits) come: zebibit (Zibit, 2⁷⁰ bits) and yobibit (Yibit, 2⁸⁰ bits). These are defined in the IEC 80000-13 standard but have no current practical applications. The IEC binary prefix family deliberately mirrors the SI prefix family, ensuring consistent naming as computing scale continues to grow.
How much data do exascale supercomputers like Frontier and Aurora move?
Frontier (Oak Ridge, 2022) achieved 1.194 exaFLOPS, with its Slingshot-11 fabric moving data at aggregate rates measurable in exbibits per second across 9,408 nodes. Aurora (Argonne, 2024) targets similar throughput with over 63,000 GPUs. At these scales, a single checkpoint of a full-system simulation can exceed 1 Eibit of state data, making exbibit a natural unit for describing I/O bandwidth requirements.
Will data measurement standards need prefixes beyond yobi-?
The IEC currently defines up to yobibit (Yibit, 2⁸⁰ bits). In 2022, the SI system added ronna- (10²⁷) and quetta- (10³⁰), but the IEC has not yet created matching binary prefixes (ronnibit? quettibit?). With global data creation projected to exceed 1 yottabit annually by the 2030s, pressure is mounting for the IEC to extend the binary prefix family — though the naming convention ("ronnibi-"?) remains an open question.
