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.
