Hello,

I have a board with an onboard SATA2 connector. I put a SATA2 disk on it,
and when I installed vista (with the controller in SATA mode in the bios
(asrock 939Dual-SATA2 board)), Vista detected the controller and loaded a
default driver, and the install took about 3 hours. The windows
experience disk performance rating was 2.2.

I changed the controller mode to IDE in the bios (which required a
reinstall of Vista), but it was way way faster. Now I have a disk
performance rating of 5, but the disk is running in IDE UDMA-6 mode
(equiv to SATA150).

I suppose the question is, does anyone know if a suitable SATA2
controller driver exists for Vista that doesnt suck the way the
controller driver that is bundled with Vista does?

I would like to be able to harness the full speed of the SATA2 disk that
is in my system.

Thanks,

JMicron has a driver for the JMB36x that's dated 2/2007 and is supposed to
be for Vista -- http://www.jmicron.com/Driver.htm

If the drive is already running in UDMA 6, though, is it likely that
you'll see any improvement in disk performance? Please post your before
and after results.



It should just be an update to the disk controller driver, reboot, and
change the setting in the bios, and then let the machine come up .... I put
a lot of time into setting up vista already and dont want to lose that
investment of time.

so ... I might, I might not.

if I DO, I will do some performance before and after, just to see if there
is a significant difference.
