How Much Data Can 1 Gbps Transfer Per Day?

A 1 Gbps link can theoretically transfer 10.8 TB in 24 hours at continuous full utilization.

The calculation

1 Gbps ÷ 8 = 125 MB/s. Over 86,400 seconds, that is 10.8 TB using decimal units.

Real-world planning

At 90% sustained efficiency, the same link moves about 9.72 TB/day. At 80%, about 8.64 TB/day.
