Data Transfer Capacity Calculator
Enter a network speed to see how much data the link can theoretically move per hour, day, week and 30 days. Apply an efficiency factor for planning.
Per hour450 GB
Per day10.8 TB
Per week75.6 TB
Per 30 days324 TB
100% shows the theoretical line-rate maximum. Reduce efficiency for a more conservative planning estimate.
How much can 1 Gbps transfer per day?
At full theoretical utilization, a 1 Gbps link carries 125 MB/s, which is 10.8 TB over 24 hours. Real sustained throughput is normally lower, so capacity planning should include measured efficiency and competing traffic.
Capacity is the inverse of transfer time
Transfer-time calculators start with a fixed amount of data. Capacity calculations start with a fixed link speed and time window, making them useful for migrations, replication and backup planning.
