When the card has an

the built in AMD ports.

So we've got the crap drives on the crap controllers ... would it make 
any difference if you put the Greens on the motherboard, and the Caviars 
on the Marvell? Caviars I believe are good quality drives that might 
take enough load off the Marvell to enable it to work sort-of okay ...

Oh - and replace the Greens pretty soon - I don't know how they compare 
against other drives quality-wise, but they are optimised in a raid 
anti-pattern.
