According to a bulletin on the OCZ site;
AHCI
AHCI is not official supported on OCZ SSDs and may under some circumstances affect performance,
specifically during windows installation. Enabling AHCI can result in higher performance in synthetic
benchmarks for SSDs and HDDs alike, but can cause hang-ups and intermittent freezes in SSDs since it allows multiple access requests to compete for a drive that is not made to address re-ordering of commands in the queue. We recommend AHCI is set to disabled in both Windows and in the BIOS.
Native Command Queuing greatly increases the performance of standard rotational drives but it has no bearing on SSDs.
With AHCI on; my drive score went from 7.1 to 7.3, but my computer became unusable from the same symptoms quoted in the bulletin.
As for my overall WPI score; it is limited to 4.4 because of the over emphasis on Aero Performance. I have not invested in a graphics card, nor do I need to. If not for the low Aero score I would rate a 5.9; My processor gets a 6.7 and memory, a 5.9 - I'll upgrade the RAM some time soon.
