Re: Raid 0 and Sata III
SATA ports (unless you are using a port multiplexer) are independent, but a single PCI-E x2 lane offers somewhat less than one full SATA 3 channel performance.

A chipset integrated controller often has better throughput than a card (since the chipset controller is on the NB-SB transport link) - though in the case of the AMD SB850 southbridge, this link has the performance of a PCI-E x4

Of course, chipset RAID is usually CPU assisted, though for simple RAID 0, there are no parity calculations
