About Pebibytes
A pebibyte (PiB) = 2⁵⁰ bytes = 1,125,899,906,842,624 bytes (IEC 80000-13). The Frontier exascale supercomputer (ORNL, 2022) has ≈700 PiB of Lustre file system storage across 5,408 HPE EX nodes. IBM Spectrum Scale HPC deployments manage 10-100 PiB namespaces. NASA's active Earth observation archive ≈ 100 PiB. All hyperscale cloud storage combined ≈ 300,000 PiB = 300 EiB as of 2024. 1 PiB = 2⁵⁰ bytes = 1,024 TiB.
About Nibbles
A nibble is exactly 4 bits = half a byte, representing 2⁴ = 16 values - one hexadecimal digit (0-F). Used in BCD encoding (each decimal digit = 1 nibble; 2 nibbles per byte packs two BCD digits), financial/mainframe packed-decimal formats, and CSS hex colours (#RRGGBB = 2 nibbles per channel). 4-bit processors (Intel 4004, TI TMS1000) processed one nibble per cycle. 1 nibble = 4 bits = 0.5 bytes.
