I was wondering if thiese results could be improved with an addon raid card vs onboard

Unlikely. RAID-0 really doesn't take any real CPU time to process, so there's not much to offload to a hardware RAID controller. It's really only when you get into RAID-5 or RAID-6 that CPU time starts to become more than trivial.

Out of curiosity, how much are you using your array?

If it scaled perfectly, you'd get ~800 read and 300 write.



Well when you say how much am I using it I could not say I can say that COD MW2 and Crysis loads in seconds :)

To be realistic, perfect scaling requires all of the I/Os to be issued on exactly the right sectors at exactly the right times. You can get it in a benchmark program designed to do that, but you'll never achieve it in real life.

You also have to consider that even though RAID can increase transfer rates, it really doesn't improve the access times - so performance that depends on random I/Os doesn't really improve much at all.
