Convert Mebibytes per second to Petabytes per second
Convert Mebibytes per second (MiB/s) to Petabytes per second (PB/s) instantly and accurately.
Conversion Formula
PB/s = MiB/s × 1.048576000e-9
About Mebibytes per second
Mebibyte per second (MiB/s) = 2²⁰ = 1,048,576 B/s (IEC 80000-13). Used in Linux fio/dd benchmark output. Optical disc speeds: CD-ROM 1× = 150 KiB/s; 52× ≈ 7.62 MiB/s; Blu-ray 1× ≈ 4.39 MiB/s; 12× Blu-ray ≈ 52.73 MiB/s. SATA II effective throughput ≈ 286 MiB/s. microSD A1 spec = 10 MB/s ≈ 9.54 MiB/s. 1 MiB/s = 1,048,576 B/s = 8 Mibit/s.
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.
