Convert Petabytes per second to Exabytes per second
Convert Petabytes per second (PB/s) to Exabytes per second (EB/s) instantly and accurately.
Conversion Formula
EB/s = PB/s × 0.001
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 Exabytes per second
Exabyte per second (EB/s) = 10¹⁸ B/s (SI). Total global storage write-throughput of all data centres combined in 2024 ≈ 1 EB/s in aggregate - but no single system or link approaches this. A single-mode fibre C-band Shannon limit ≈ 15 Tbit/s; reaching 1 EB/s = 8 Ebit/s would need ≈ 500,000 such fibres. 1 EB/s = 10¹⁸ B/s = 8 Ebit/s.
