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 Tebibit (Tib)
A tebibit (Tibit) equals exactly 1,099,511,627,776 bits (2⁴⁰ bits) in the IEC binary system. It is 9.95% larger than the decimal terabit (10¹² bits). Tebibits appear primarily in enterprise and hyperscale storage engineering, high-speed interconnect specifications (InfiniBand, PCIe), and NAND flash die capacity ratings. At this scale, the gap between decimal and binary units is nearly 10% — significant enough to affect storage procurement decisions and network capacity planning in large deployments.
High-density NAND flash wafers are sometimes characterized in tebibits per die. A 1 Tibit capacity is equivalent to 128 GiB of storage.
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.
Tebibit – Frequently Asked Questions
What is the difference between terabit and tebibit?
A terabit (Tbit) = 10¹² bits (SI decimal). A tebibit (Tibit) = 2⁴⁰ bits = 1,099,511,627,776 bits (IEC binary). Tebibit is 9.95% larger. At enterprise storage scale, this 10% difference has real financial consequences: a storage specification error confusing Tbit with Tibit on a 100-unit deployment results in nearly 10 units' worth of capacity discrepancy.
Where are tebibits used?
Tebibits appear in: NAND flash memory die specifications and yield calculations, high-speed fabric interconnect specifications (InfiniBand HDR = 200 Gbit/s), supercomputer storage system designs, and academic papers on distributed storage systems. Consumer applications never display tebibits; the term is confined to engineering and procurement contexts.
How is 3D NAND flash capacity measured in tebibits?
Modern 3D NAND stacks 100+ layers of memory cells vertically. A single die from a 232-layer TLC NAND chip can hold about 1 Tibit (128 GiB) raw capacity. Manufacturers measure at the die level in tebibits because binary addressing maps directly to the physical array geometry — each layer, block, and page aligns to powers of 2. A 16-die package thus holds 16 Tibit (2 TiB) before error correction overhead.
Why does the SI vs IEC gap grow as units get larger?
Each binary prefix multiplies by 1,024 instead of 1,000. The compounding effect: kibi vs kilo = 2.4% difference, mebi vs mega = 4.9%, gibi vs giga = 7.4%, tebi vs tera = 9.95%, pebi vs peta = 12.6%, exbi vs exa = 15.3%. The difference grows by approximately 2.4% with each prefix step, making precision in naming increasingly important at larger scales.
How do I convert tebibits to terabytes?
1 Tibit = 2⁴⁰ bits = 2⁴⁰ / 8 bytes = 2³⁷ bytes = 137,438,953,472 bytes ≈ 137.4 GB (decimal). To convert Tibit to GB: multiply by 137.4. To convert Tibit to GiB: divide by 8 (since 1 Tibit = 0.125 TiB = 128 GiB). The exact value: 1 Tibit = 128 GiB.
