Conversion Formula
EiB/s = PB/s × 0.000867361738
About Petabytes per second
Petabyte per second (PB/s) = 10¹⁵ B/s (SI). Theoretical for single systems. NTT 2024 fibre lab record = 191 TB/s ≈ 0.19 PB/s. Exascale HPC with 10,000 nodes × 10 TB/s memory bandwidth each = 100,000 TB/s = 100 PB/s in aggregate - plausible as a cluster total but not a single link. Global all-data-centre combined write throughput ≈ 1-10 PB/s. 1 PB/s = 10¹⁵ B/s = 8 Pbit/s.
About Exbibytes per second
Exbibyte per second (EiB/s) = 2⁶⁰ B/s ≈ 1.153 × 10¹⁸ B/s (IEC 80000-13). Total global data-centre write throughput in 2024 ≈ 1 EB/s ≈ 0.87 EiB/s in aggregate across all systems - but no single link approaches this. Shannon limit for a single-mode fibre full C-band ≈ 15 Tbit/s; reaching 1 EiB/s requires ≈ 500,000 such fibres. 1 EiB/s = 2⁶⁰ B/s ≈ 8 Eibit/s.
