Is anyone having slow SATA performance on their 09 mac pro in bootcamp. Just booting into windows takes a long time and trying to burn a disc or transfer something to an external hard drive takes a long time. I created a large iso file and burned it to a BD-50 RW disc in windows and it took approximately 4 hours and it was set to burn at the fastest speed which should of been 2x but never reached any faster than 0.7x. I burned the same iso in mac osx through disc utility and it took less than 2 hours. I transferred the same iso file to an external usb hard drive in windows and that took 4 hours which is extremely slow. Does anyone know how to get SATA operating at a normal speed. I checked in the device manager and it is set to operate in DMA mode.
Got a tip for us?

I had roughly the same type of issue when I first got my 1st Gen MP 2.66. The problem for me, and probably for you, is lack of appropriate drivers in your XP install. In order for me to fix the problem, I had to slipstream the proper MB chipset drivers into m XP iso image. Once I did that, everything worked great.

I wonder if it's this one:

I'd be astonished if there's another issue with SATA/IDE controllers and
Mac Pro firmware. I mean, wow, how many times can Apple get it wrong?
Thanks, I have the hard drive that windows is on in bay 4 and I will place the drive in bay 2 and will post my results.
The link in #5 is the best cure for the problem. When you throw out the legacy drivers and run the 4 HD in AHCI mode you also get the two unused ODD-SATA ports which can be used as additional HD ports or for a Blu-Ray under Windows.
