The 3Ware RAID cards I have vastly outstrip the motherboard built in Intel RAID 
implementations for a RAID 5 setup. (I don't consider RAID 1 to be economically 
sensible for most uses.) A four disk RAID 5 SSD configuration can be 
breathtaking fast, too.

Don't think they'll be upgrading it to 12Gbps (not that many people are interested in real RAID-supporting cards at such speeds, these are mostly for connecting external storages...)
