About Zettabits
A zettabit (Zbit) = 10²¹ bits (SI). Global internet traffic crossed 1 ZB/year ≈ 2017; projected to reach 72 Zbit/year by 2030. IDC estimates global data created/consumed could reach 1,400 Zbit/year by 2025 (mostly transient). The theoretical capacity of all installed submarine fibre, running simultaneously at state-of-the-art spectral efficiency, approaches several Zbit/s. 1 Zbit = 10²¹ bits = 125 EB.
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.
