Is large bandwidth limit traffic or small bandwidth unlimited traffic more suitable for you?

It’s 2024 now, and recently I’ve come across the question of whether to choose a large bandwidth limit or a small bandwidth limit when buying a machine. I feel that to explain this clearly, all we need to do is highlight one basic physical concept: 1Mbps bandwidth, which means transmitting 128KB of data per second. I hope that by using a relatively extreme example, we can help newcomers understand which is suitable for them.

Extreme assumptions: On average, each page of the website contains 10 1MB images. There are two servers available for you to choose from: 5M bandwidth unlimited traffic and 1Gbps bandwidth limited to 1.65T traffic. Even with the same price, assuming that the visitor’s bandwidth is infinite.

The limit of 5M bandwidth is 5*128K per second. It takes more than 15 seconds to load a 10MB web page, while 1Gbps bandwidth takes only 0.078 seconds to load a web page. Your visitors will tell you the answer.

You find that the total accumulated data on the website has been packaged to 500GB, and you need to back up remotely or download it to your personal computer for backup. Backing up on a machine with 1Gbps bandwidth took only 65 minutes, but on a machine with 5Mbps bandwidth, you may find that it seems to take many days to complete the backup. You have your own answer.
