The generic advice in the RAID HOWTO is not to put more than one IDE drive
per ribbon cable. It would appear that RAID is not worthwhile with your
current configuration. A low cost PCI-IDE controller, mentioned recently,
would be a way of providing a 3rd channel.
The performance improvement that I've measured with software RAID 0 varied
from near linear to actual decrease. It appears to be dependent on the IDE
sub-system of the mobo.
Perhaps try a trial RAID 0 with only one drive on each ribbon and see what
performance you measure via "hdparm". If the results are unimpressive, then
its probably a hardware/firmware limitation and varying partitioning may not
give much improvement either.
The SuSE Ref Manual has some interesting advice re partitioning for
performance. I don't currently have the manual installed, but In essence,
the strategy is to pick large, busy, sub-directories eg /usr/X11R6,
/var/spool and put those in separate partitions at the beginning of
