Hmm, on most newer mainboards there are 4 sata ports. For
better performance I would suggest you use that instead of a  separate
osata controller.

I would suggest you put a little (say 10 GB in total of your big disks)
for your system, in a raid setup - to provide against crashes.
Also put your swap on raid to prevent crashes if a single disk 
breaks down.
