About Yobibytes
A yobibyte (YiB) = 2⁸⁰ bytes ≈ 1.21 × 10²⁴ bytes (IEC 80000-13) - the largest named binary byte unit (2008 edition); 2022 revision added 'ronbi' (Ri, 2⁹⁰) and 'quetti' (Qi, 2¹⁰⁰). At HAMR areal density (10 Tbit/inch² projected by 2030), 1 YiB would require ≈ 6.24 million km² of magnetic platter surface - modestly exceeding the area of Australia. World total storage in 2023 ≈ 0.00848 YiB. 1 YiB = 2⁸⁰ bytes = 1,024 ZiB.
About Kibibytes
A kibibyte (KiB) = 2¹⁰ = 1,024 bytes (IEC 80000-13) - the binary kilobyte used by OS memory management. Linux/Windows page size = 4 KiB (4,096 bytes); default NTFS/ext4/APFS cluster size = 4 KiB. CPU L1-D cache: 16-64 KiB. Arduino AVR flash: 2-32 KiB. Windows labels KiB as 'KB'. 1 KiB = 1,024 bytes = 8,192 bits.
