There is no sensible way to get 2 Gbit/s as maximum transfer limit.
Afaik, the fastest FX gigabit networks cards can deliver roughly 1Gbit/s.
Unless there is some incredibly fancy and stunningly fast software that can merge two network cards into one outbound line...?
In terms of speed for 2GB of monthly transfer, 2GB/m equals exactly 2Kbit/s of steady speed for an entire month...
Most harddrive setups wouldn't be able to hit 2Gbps
To the poster, ask your provider how fast a port you have on your server. 2GB is your overall limit and has nothing to do with the speed of your transfers. The biggest factors that will affect your transfer rate are:
1. Port speed
2. Networks its connected to
3. How far away you are from the server
