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 Kilobytes
A kilobyte (KB) = 1,000 bytes (SI). Used by all storage manufacturers (HDD, SSD, USB, SD) and endorsed by the IEC and FTC. Typical sizes: plain-text email 2-5 KB; HTML page 10-100 KB; Word document 10-30 KB. Ethernet MTU = 1,500 bytes ≈ 1.5 KB; jumbo frames 9 KB. MP3 at 128 kbit/s = 16 KB/s of audio. 1 KB = 1,000 bytes = 8,000 bits.
