I've just installed a new Samsung 830 256GB SSD and have configured BootCamp with Lion and Windows 7.

Under Lion, I have installed Trim Enabler.

Under Windows 7 I have installed the Samsung (Wizard) software that came with the SSD. In this software I've applied all of the recommended optimisations under 'OS Optimisations', however, the Samsung wizard software is informing me that AHCI is not enabled at present and for best performance, this should be enabled.

I'm not sure a) what implications there are if it's left disabled (will it affect the lifespan of the SSD or is it purely a speed thing?) and b) if there is a way under BootCamp for an Early 2011 MacBook Pro to have AHCI enabled?

I was also concerned that if AHCI is not enabled, perhaps TRIM won't be enabled either? However, I did run a tool which I found online that said that TRIM was enabled on this Windows 7 install (despite AHCI not being enabled).

This is my first SSD drive so am not very familiar with the technology, terminology and best practices etc.

In windows go to Control Panel\System and Security\System, click on the "windows experience" link and "Re-Run the assessment" this will update info about the drive and enable trim.
