<speculation>Two is better than one. Iterate that a few times and you've got 
four. I don't immediately see the advantage of the additional connectors 
since you can't combine the 4 drives you might connect into a single array, 
only as two separate arrays. Hey, but you could GEOM across controllers. I 
haven't tried any performance measurements on the one controller or the other 
-- I'm pleased that I can move the array from one controller to another and 
that it works, that's enough for me.</speculation>

<apropos>Sil (e.g. the Sil3114 on the nForce4-based Asus A8N-SLI) isn't 
supported beyond "generic ata", right? I've not seen it mentioned in the 
hardware notes for ages.</apropos>
