ajb - i have never heard of maxtors being described as quiet drives, but I'm prepared to be proven wrong. The quiet drives (of the iyonix generation) were the seagate units. I know the Mpro3 author switched his maxtor for a seagate to reduce system noise. Samsungs are also pretty quiet. Western dig introduced fluid bearings too, but I never really noticed a significant noise reduction. I do notice that different drives (even from same range) seem to vary considerably in noise levels, so I think it is hard to pinpoint this stuff. Sorry to bang on about the maxtors - it may just have been several bad batches of the 7200rpm drives that i've come across.
