Fire of Youth - the data throughput of a gigabit network (1000 Megabit) is approximately 100 Megabytes per second (1000 Megabit/8 bits per byte is 125 Megabytes) That is currently the fastest network speed found in homes. Many devices though are still "Fast Ethernet" meaning 100 megabits per second or 12 Megabytes per second. Until the last half dozen years of so, this was the top speed in most home. Many devices state they have a 10/100 port meaning 10 Megabits per second/100 Megabits per second.

Remember it takes 8 Megabits (Mb note lower case b) to make a Megabyte (MB note upper case B).

Wireless G has an over the air transmission speed of approximately 54 Megabits/sec which translates to approximately 5 Megabytes (MB)/sec. If you are using wireless N, then it is up to 6 times faster, but even that is far slower that the wired gigabit network speed, This is why the recommendation that the connection from the NAS to your TV be wired all the way, even though it is more trouble and expensive to run the wire. No matter how fast the NAS is, if you are using wireless, your speed will be limited to the wireless speed.
