Overview
When choosing a server, have you noticed the bandwidth parameter? For example, 1G bandwidth or 10G bandwidth. Many people mistake these bandwidth figures for download speed, but that is actually incorrect.Server bandwidth refers to the amount of data that a server can transmit per unit of time (usually 1 second), typically measured in Mbps (megabits per second) or Gbps (gigabits per second). It determines the server's data transfer speed and directly affects the smoothness of user experiences such as website access, file downloads, and video streaming.
| Bandwidth (Mbps) | Theoretical Download Speed (MB/s) | Actual Download Speed (approx.) | Use Case |
|---|---|---|---|
| 1 Mbps | 0.125 MB/s | 100~120 KB/s | Text chat, low-quality video |
| 5 Mbps | 0.625 MB/s | 500~600 KB/s | HD video, standard websites |
| 10 Mbps | 1.25 MB/s | 1~1.2 MB/s | Online 4K video, multi-user office |
| 50 Mbps | 6.25 MB/s | 5~6 MB/s | Small business websites, game servers |
| 100 Mbps | 12.5 MB/s | 10~12 MB/s | Medium to large websites, video streaming |
| 1 Gbps (1000Mbps) | 125 MB/s | 100~120 MB/s | Large data centers, high-concurrency servers |
With this in mind, here is a reference for selecting server bandwidth based on your business needs:
Personal blog / small website: 5~10 Mbps
E-commerce website / enterprise applications: 50~100 Mbps
Live video streaming / game servers: 100 Mbps~1 Gbps
