Speeding up Firewire File Transfers?

Milo_Mindbender asks: "I've got a pretty common problem: copying a ton of files from an old Windows XP computer to a new one. After noticing how long transfers were taking over my 100mbps Ethernet, I hooked up a IEEE1394/Firewire cable and things were much faster. Strangely though, Windows is still only using about 10% of the cable's 400mbps bandwidth. Does anyone know any tips/tricks for speeding this up or any Shareware mass-file-copy tools that would be faster than Explorer/file sharing? Right now, the older machine is setup with Windows file sharing and the new machine is copying from it, neither machine is using much CPU and the disks are nowhere near their max speed. The number and size of the files might be what's slowing it down, since it's gigabytes of files in the 100-200k size range."

File size is the problem

[inio]

Your file size, and disk seek time, are the problem. Lets say your drive has a 5ms seek time (that's pretty damn fast). writing each file actually requires three writes: to the file allocation tabe, to the directory, and the contents of the file itself. Assuming the writes take another 5ms, that's 20ms per file. that limits you to 50 files per second. At 200kiB per file that's about 10 megs per second.
