LinuxQuestions.org - ieee 1394 and linux

i have an external hd i can use it plugging on usb or a firewire ports using a little usb cable to aliment it.

my laptop hasn't any usb2 so the best in my case was the ieee 1394 port.

but actually testing the transfer rate with this prompt command:

Code:

hdparm -tT /dev/sda

this is te result when plugged on firewire:

Code:

/dev/sda:

 Timing cached reads:  1204 MB in  2.00 seconds = 601.49 MB/sec

 Timing buffered disk reads:    2 MB in 211.91 seconds =  9.66 kB/sec

this is the result when plugged on usb1

Code:

/dev/sda:

 Timing cached reads:  1172 MB in  2.00 seconds = 585.50 MB/sec

 Timing buffered disk reads:    4 MB in  5.00 seconds = 819.65 kB/sec

pretty strange no?

i hope you can help to get the full tr
