Connection speed

Speed unit

Home broadband (100 Mbps)100 Mbps = 12.5 MB/s

Gigabit fiber (1 Gbps)1 Gbps = 125 MB/s

USB 3.0 raw line rate5 Gbps = 625 MB/s

SATA SSD~560 MB/s

NVMe SSD (PCIe 3)~3,500 MB/s

NVMe SSD (PCIe 4)~7,000 MB/s

Ethernet LAN (1 GbE)1 Gbps ≈ 125 MB/s

4G LTE average~30 Mbps = 3.75 MB/s

5G peakup to 10 Gbps

Exact unit rule: 1 byte = 8 bits. Mbps means megabits/s; MB/s means megabytes/s. Device and mobile rows are illustrative nominal/typical figures from the preserved 2024 snapshot, not guaranteed current or real-world throughput; protocol overhead reduces usable speed.
