I recently got an OCZ Vertex 2 SSD for my Spring 2010 i7 MacBook Pro and am having issues getting AHCI working reliably under Windows 7 x64 in Boot Camp. Following the instructions outlined here I've tried the following:

  1. In the Windows registry changed HKLM\System\CurrentControlSet\Services\msahci\Start, HKLM\System\CurrentControlSet\Services\iaStor\Start, and HKLM\System\CurrentControlSet\Services\iaStorV\Start to 0.
  2. Reboot into OS X and use the AHCI Enabler application to enable AHCI via the MBR.
  3. Reboot back into Windows, which detected the controller as AHCI and installed the msahci.sys driver.

This significantly increased the performance, but at the cost of stability. Under the MS AHCI driver Windows will BSOD when resuming from sleep. I tried installing the Intel RST drivers (both 9.6 and 10.1), but they consistently caused 2 BSODs just booting the system in addition to the resume issue (3rd restart would work).

It looks like I'm not the only one experiencing the BSOD issue. In the short term I can disable sleep, but the fact that it happens at all due to the storage drivers makes me very uneasy trusting the system. Please help me get the most out of my SSD!
