ahci not officially supported by ocz

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.
getting an ocz ssd
so do i alter bios to achi or leave it at ide?
thanks

Where did you read that? OCZ staff at the official forums consistently recommend AHCI for Vertex 2(E) drives. That statement is probably about their earlier Indilinx based SSDs.

I've not had any issues with AHCI enabled. Like was said its probably about older ssd's.

Indeed. I have had no problems with AHCI and my OCZ SSD.

According to OCZ, to flash their drives with new FW the system has to be set to IDE.

Must be a common thing, as I have just done my C300, and the update couldnt find the drive while in AHCI mode.

Im running my Vertex 2E on IDE Enhanced mode and have no problems at all... Detected everytime at boot and runs like a bat out of hell

If I need to update the firmware then im in trouble as I don't have an AHCI mode on the board im using at min. Seems sometimes they work in AHCI mode and other times they need IDE mode. Reminds me of a girl I used to know

It should work in both modes. I've flashed mine twice in AHCI mode. Certain AHCI drivers aren't supported though, like Intel RST 10 series.
