sorry i'm not quite sure where this thread belongs, so please move this if necessary. i've been reading about problems in mac pro and past BootCamp versions, esp regarding SATA performance issues. my understanding is that there's 2 modes: PIO and DMA; and DMA has better performance (esp under Ultra DMA). i know that this affects Windows, but is it the same for Mac's? how does one go about finding out if my SATA is PIO or DMA in OSX? is it benefitial to change to DMA (if it's possible)?
