I enabled ahci in th ebios, installed windows 7. then I installed the intel rst drivers. but when I run as ssd benchmark it says pciide-OK, shouldnt it say iastor-ok or something to that effect? does this mean ahci is somehow not enabled. I checked the registry; msahci start is set to 0
 
ok I found in the bios the MArvel controller was set to run in ide mode, I changed it to ahci, now it is showing the msahci driver. I installed intel RST but it does not switch to iastor automatically. Is there a trick to switch?
 
I think I figured out my issue. My motherboard has the marvell controllers and I heard they have problems getting to full sata3 speeds,

You could always just connect the SSD to your SATA 3Gbps ports that are controlled by the Intel chipset. You'll sacrifice some top-end on the reads and writes, but for most real-world scenarios you won't notice the difference.

oh well, this is no good. Should I return the ssd since I am not getting full performance out of them?

No. Swap over to an Intel port, make sure it's using AHCI, and go on about your computer use. If it already boots up with MSAHCI, you should not need to do anything but swap ports. In real application performance, the Intel controller will best the Marvell, even if limited to about 270MB/s sequential transfers.
