Conversion Formula
ZB = YB × 1000
About Yottabytes
A yottabyte (YB) = 10²⁴ bytes (SI) - among the largest original SI named powers. Global annual data generation forecast ≈ 175 ZB = 0.000175 YB by 2025 (IDC) - a yottabyte equals ≈ 5,700 years of data production at 2025 rates. Claims of multi-YB NSA data centres were debunked; credible estimates: 3-100 EB. Erasing 1 YB at the Landauer limit (300 K) would require ≈ 182 J - enough to heat 0.4 mL of water by 1°C. 1 YB = 10²⁴ bytes = 1,000 ZB.
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.
