Given the > choice, I would prefer USB2 over firewire. I purchased a Maxtor 500DV 200GB external USB2/firewire hard drive, and under shrike / kernel 2.4.20-19.9 from my Dell Inspiron 8000 I get 11MB/s (hdparm -t or time dd) when I plug it using USB2 (through a PCMCIA NEC UDB2 adapter) and 21MB/s when I plug it on firewire. Published benchmarks (under other OSes :) show 25 to 35 MB/s. Since I don't need much performance (main use is backup) I leave it plugged on USB2 because it seems to survive much better plug/unplug than firewire (where I have to play with rmmod and sometimes reboot to get it back). Will newer Red Hat releases / kernel versions get better performance and plug/unplug behaviour? Any other user experience with this drive? Thanks in advance (and sorry if it's the wrong list).
