You did not take into account the underlying protocol overhead, including TCP/IP and the application protocol. Also, on an ethernet segment, only one sender (source, destination) may talk at a time, which adds further overhead to the protocol overhead.
Plus, you did not take into account bus, OS and filesystem readwrite latency on both ends. The list goes on and on. It not possible to do a simple math calculation to determine the transfer rate of the actual data.
If you have a superfast system where the bus, IO, disk latency were insignificant, you would still have significant TCP/IP overhead.
