Conversion Formula
PiB/s = PB/s × 0.8881784197
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 Pebibytes per second
Pebibyte per second (PiB/s) = 2⁵⁰ B/s ≈ 1.126 × 10¹⁵ B/s (IEC 80000-13). NTT's 2024 lab record (1.53 Pbit/s ≈ 191 TB/s ≈ 0.17 PiB/s) is the closest any physical link has come. An exascale cluster with 10,000 nodes × 10 TiB/s each ≈ 97.7 PiB/s aggregate - approaching this range in the aggregate, not a single link. From a physics standpoint, requires ≈ 10 million NVMe SSDs in parallel. 1 PiB/s = 2⁵⁰ B/s ≈ 8 Pibit/s.
