actually, if you are going to have concurrent connections to the backend,
in some circumstances, PostgreSQL will handle multi-processors better then

my preference tends to be software raid...whatever I've ever seen as far
as hardware raid is concerned has been quite slower then software
raid...and this is with high-end servers...
