About Gibibytes

A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.

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.
