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 Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
