About Megabits per second
Megabit per second (Mbit/s) = 10⁶ bit/s (SI). Standard consumer broadband unit: ADSL2+ up to 24 Mbit/s; VDSL2 up to 100 Mbit/s; Wi-Fi 6 up to 9,608 Mbit/s; Gigabit Ethernet = 1,000 Mbit/s. Streaming: Netflix 1080p = 5 Mbit/s; 4K HDR = 15-25 Mbit/s; 4K Blu-ray up to 128 Mbit/s. ISP 100 Mbit/s ≈ 12.5 MB/s download. 1 Mbit/s = 10⁶ bit/s = 125 KB/s.
About Bytes per second
Byte per second (B/s) = 8 bit/s. The natural unit for file transfer speeds, disk I/O, and memory bandwidth reported by OS tools and storage benchmarks. ISP 'Mbit/s' ÷ 8 = MB/s download speed: a 100 Mbit/s connection delivers ≈ 12.5 MB/s. USB 2.0 = 60 MB/s; SATA III = 600 MB/s; Thunderbolt 4 = 5,000 MB/s. 1 B/s = 8 bit/s.
