Interesting.  I have the same motherboard in a few new test machines and 
we ended up going with Highpoint RocketRAID 2224 cards.  We used these 
because they supported 4 internal drives and had a multilane/infiniband 
connector on the bracket for an external tank of 4 additional drives.  I 
haven't experienced any performance problems with either the internal or 
external drives (Seagate 500gig SATAII all around).  I did have a couple 
of drives that seemed to be in "popcorn popper mode" under heavy usage 
when NCQ was enabled so I turned it off and it went away (not really an 
issue for me since these boxes are just pushing around a lot of huge 
uncompressed video files and not doing any significant seeking).

I had initially planned on going with 3Ware boards as I've had great 
success with them in the past, but some of our video editing folks 
wanted the ability to cart around shoeboxes with 2TB in 
them...sneakernet style.
