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.
About Zebibits
A zebibit (Zibit) = 2⁷⁰ bits ≈ 1.18 × 10²¹ bits (IEC 80000-13). Total world manufactured digital storage in 2023 (≈ 10,000 EB ≈ 80,000 Ebit) is ≈ 67,000× smaller than 1 Zibit. A 70-bit byte address space would address 2⁷⁰ bytes = 128 ZiB of memory - far beyond any foreseeable architecture. At projected HDD areal density (10¹² bits/cm²), 1 Zibit would require ≈ 10⁹ cm² ≈ the area of Iceland. 1 Zibit = 2⁷⁰ bits = 128 EiB.
