In REAL WORLD USAGE, you will NOT get 320GB out of 1Mbps unless you some how "MAGICALLY" push 1Mbps 24/7 for the entire month without ONCE going below 1Mbps.
If your traffic has peaks and drops, like I guarantee it does (day time and night time for example), you will not get 320GB out of 1Mbps.
The average real world usage figures are about 150-220GB (again depending on each servers individually specific traffic patterns) per 1Mbps.
So, 10,000GB divided by 220GB = 45Mbps.

The less GB's you get out of each 1Mbps, the higher Mbps amount the 10,000GB will equate to. The only person that is bad for, is the host as they are giving you more Mbps for the same amount of transfer (10TB).
