It depends on the device you are writing to. A single hard drive will usually have a maximum transfer rate of 75-100MBps which is 600-800Mbps. FW800 is 800Mbps so can work with the fastest rate the drive can take.
If your drive only reaches 40MBps = 320Mbps then you're not going to see much difference between FW400 and FW800. If on the other hand you target an external RAID setup where transfer rates are 150MBps (1200Mbps) and above, that's where FW800 and eSATA are needed.

Of course, you will be limited by your read speeds if you transfer from a slow drive.
