About Kilobytes per second
Kilobyte per second (KB/s) = 1,000 B/s = 8,000 bit/s (SI). Legacy modem throughput: 56 kbit/s dial-up ≈ 7 KB/s; ISDN 128 kbit/s = 16 KB/s. RS-232 at 115,200 baud (8N1) = 11.52 KB/s. CD-ROM 1× = 150 KB/s; 52× = 7,800 KB/s. Bluetooth 2.1 EDR ≈ 300 KB/s; USB 1.1 Full Speed = 1,500 KB/s. 1 KB/s = 1,000 B/s = 8 kbit/s.
About Kibibytes per second
Kibibyte per second (KiB/s) = 2¹⁰ = 1,024 B/s = 8,192 bit/s (IEC 80000-13). Used in embedded I/O specs and real-time OS throughput documentation. SD card speed classes: Class 10 = 10,000 KB/s ≈ 9,766 KiB/s; UHS-3 = 30,000 KB/s ≈ 29,297 KiB/s. STM32F4 FLASH page write ≈ 16 KiB/s; Arduino Uno SPI at 4 MHz = 500 KiB/s. 1 KiB/s = 1,024 B/s = 8,192 bit/s.
