Installed SSD in T500... Intel Matrix driver?

Question

I replaced my 7200RPM drive with a OCZ Vertex 2 180GB unit. All the System Update drivers installed fine, but the Intel Matrix Storage Manager driver for WIndows 64bit will not install. I only have one drive in the system, do I need this package? I read that the latest version is named Intel Rapid Storage Technology.
It's not the greatest SSD, but it's making my life easier at the moment. I'm setting up backups to a network appliance just in case it experiences a random failure. Here are the winsat numbers:

Answer 1

To be honest, I don't see what it actually does. Windows 7 seems to driver the SATA stuff fine out of the box. I don't have it installed at the moment; I uninstalled it trying to diagnose a 30 second shutdown delay involving FLTMGR.SYS according to the shutdown trace. It seemed to start around the installation of the RST drivers (although it's install fine before), and is still there.
