As far as i know it is not possible as there are two separate controllers in different slots and they can not talk to each other. They will show up independent in the bios. If you raid 0 the two 500's you will have your terabyte array. I don't advise such a large array as RAID 0 only writes the data once, it does not achieve data redundancy. If one drive fails a terabyte of data is a lot to loose, if your card supports it a 4 drive raid five is one of the safest arrays
