I was wondering: having both a Promise and a VIA SATA controllers and
2 hard drives: to implement software raid, which of these
configurations would give better performance?:
1. One HD attached to a different controller (one to VIA, one to Promise)
2. Both HDs on the VIA controller
3. Both HDs on the Promise controller
I guess that using a single controller would put more load on it but
reduce the PCI bus load, and vice versa... am I right?

(Promise being a better controller)... but is it better than option 1
in overall performance on this scenario? what do you think?
Thanks
