How Long Does 1 TB Take at 1 Gbps?

1 TB takes 2 hours 13 minutes 20 seconds to transfer over a 1 Gbps link at the theoretical line rate.

The calculation

1 TB is 8,000 gigabits. At 1 Gbps, the theoretical transfer takes 8,000 seconds.

Real-world planning

At 90% sustained efficiency, 1 TB takes about 2 hours 28 minutes. Use measured throughput for important migration windows.
