About Petabyte (PB)
A unit of digital storage equal to 1,125,899,906,842,624 bytes (= 1,024⁵ = 2⁵⁰ bytes) in the binary (computing) convention, or 10¹⁵ = 1,000,000,000,000,000 bytes in the decimal (SI marketing) convention. Reference values: the global daily Twitter/X firehose ~6 TB/day = ~2 PB/year of public tweets; Netflix's total catalog encoding ~3 PB (about 14,000 titles × multiple resolutions and codecs); the entire printed collection of the US Library of Congress ~10 TB digitized = 0.01 PB (a single petabyte holds 100× the LoC); the Internet Archive total holdings ~99 PB (text + images + videos + software); Facebook/Meta photo storage adds ~600 TB/day = ~0.6 PB/day; YouTube uploads ~500 hours of video per minute = ~720,000 hours/day, generating estimated petabytes/day of new video at H.264 bitrates. The petabyte is the working unit for hyperscale cloud storage (AWS S3, Google Cloud Storage, Azure Blob), data-center file systems (Lustre, GPFS, IBM Spectrum Scale, Ceph), and scientific computing (LHC, SKA radio telescope, Square Kilometre Array, Vera Rubin Observatory).
About Gigabyte (GB)
A unit of digital storage equal to 1,073,741,824 bytes (= 1,024³ = 2³⁰ bytes) in the binary (computing) convention, or 1,000,000,000 bytes (= 10⁹) in the decimal (SI marketing) convention — the difference of 7.4% explains why a hard drive marketed as '1 TB' shows as '931 GB' in operating-system reporting. Reference values: a typical modern smartphone storage 64-512 GB (iPhone 15 base 128 GB, Pro Max up to 1 TB; Galaxy S24 base 256 GB); typical laptop SSD 256 GB - 2 TB; consumer USB flash drive 16-512 GB; the entire English Wikipedia text + images compressed ~50 GB; a 4K 60-fps movie file in H.265 ~30-50 GB for a 2-hour film; a Blu-ray disc 25 GB (single layer) or 50 GB (dual layer); the Internet Archive's Wayback Machine total ~99 PB (~99,000,000 GB). The gigabyte is the dominant working unit for consumer storage in 2020s+ technology — laptops, phones, USB drives, gaming consoles (PS5 + Xbox Series X both ship with 825 GB - 1 TB internal NVMe).
