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).
