determine firewire transfer speed

Hi,

is there a way how to determine actual transfer speed rate between IEEE1394 and connected device?

Use a copy utility that provides the transfer rate, like rsync:

rsync -av --progress --partial mybigfile.avi /media/ieee1394disk/

As the copy proceeds, the file transfer rate over the last update will be displayed. At the end of the copy, the transfer rate for the whole file will be shown.

Use time in the beginning of cp command. Then calculate the size divide by time. Use du to calcuate the estimate size.

Another suggestion, just transfer a large file, and time how long it takes. Megabytes divided by seconds equals the transfer rate. -- J.W.

Thanks for replies, but there is problem. The device is miniDV handycam that can't be mounted so "macemoneta" answer cannot be used.

I think that miniDV record is not 1:1 with final grabbed DV video file so the others answer can't be used.

The DV transfer rate is about 25-30Mb/sec, if I remember correctly. It's much lower than the interface speed (400Mb/s on ieee1394).

Thank you macemoneta.
