Conversion Formula
EiB = ZB × 867.361738
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 Exbibytes
An exbibyte (EiB) = 2⁶³ bytes ≈ 9.22 × 10¹⁸ bytes (IEC 80000-13). 2⁶³ is also the absolute value of INT64_MIN (the smallest signed 64-bit integer), making 1 EiB the natural upper limit for file systems using signed 64-bit byte offsets. File system theoretical maxima: NTFS 16 EiB; APFS 8 EiB; Btrfs 16 EiB; ZFS 256 quadrillion ZiB. Total hyperscale cloud storage estimated at 500-1,000 EiB as of 2024. 1 EiB = 2⁶⁰ bytes = 1,024 PiB.
