Just had to use this process to fully utilise my Vertex 3 240GB SSD. Before I did this it was in IDE mode and running around 300 mbps (slow). I'm now getting about 490mbps
I'm putting it on here to help others and to remind me if i need it again in future!
Steps
Go into the registry using regedit and change each of the "start" values in the registry keys below from 3 to 0 and this will allow you to change between the different modes by just changing the option in your bios each time you reboot.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\pciide
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\iaStorV
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\iaStor
You might not have the last registry key (iastor) as this is installed in the registry with the intel raid drivers, the default windows 7 raid driver uses the iastorV key.
And there you have it. Reboot, change the HDD Mode in the BIOS to AHCI and Bob's your uncle.
Cheers.
