Please, could you tell me/us if you are using that card in a PCIe x8 slot that is wired for 8x?
I have a SM H8DCE mobo that has PCIe x8 slots but they are wired as 4x. The throughput you stated (~155MBps) sounds like you might have a 4x wired slot too.
Edit: found reference to Samsung SATA300 disks so removed that question
