About Zettabytes

A zettabyte (ZB) = 10²¹ bytes (SI). The 'zettabyte era' was declared by Cisco in 2016 when annual IP traffic first crossed 1 ZB. Global IP traffic ≈ 4.8 ZB/year in 2022. Total data-centre capacity worldwide ≈ 10 ZB in 2023. Global datasphere forecast: 175 ZB/year created by 2025 (IDC). Erasing 1 ZB at the Landauer limit (300 K) would require ≈ 22.8 J - a tiny energy cost that thermodynamic limits will not bite for decades. 1 ZB = 10²¹ bytes = 1,000 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.
