I have been using the X25 80 GB G2 and have enabled the Advanced Host Controller Interface. I have windows 7 which installed its own drivers. It appears as windows 7 has installed the MSASCUI. I have installed the SSD utility which is working properly and and my rating has jumped to 400. Can anyone tell me which is better than the X25 ACHI Intel and MSASCUI so that i can keep the best one and get rid of the unwanted.
