About Zebibytes
A zebibyte (ZiB) = 2⁷³ bytes ≈ 9.44 × 10²¹ bytes (IEC 80000-13). Total world installed storage in 2023 ≈ 10 ZB ≈ 0.848 ZiB - humanity has barely manufactured enough storage to fill one zebibyte. ZFS (Zettabyte File System, 2001) was named to evoke ZB-scale ambitions; practical deployments remain far below 1 ZiB. At HAMR areal density (10 Tbit/inch²), 1 ZiB would need ≈ 60.9 million km² of magnetic surface - ≈ 12× all Earth's continents. 1 ZiB = 2⁷⁰ bytes = 1,024 EiB.
About Gigabytes
A gigabyte (GB) = 10⁹ bytes (SI). All consumer HDDs, SSDs, SD cards, USB drives, and smartphones advertise in GB. Media sizes: 4K Blu-ray 66-100 GB; 4K Netflix film 10-15 GB; modern AAA PC game 50-200 GB; Google Maps offline country data 5-30 GB. The IBM 350 RAMAC (1956) stored 0.00000375 GB; a Seagate Exos 20 TB holds 20,000 GB - 5.3-million-fold increase in 66 years. 1 GB = 10⁹ bytes = 1,000 MB.
