You will only notice the random disk access every few seconds or so if you using NTFS.
Sysinternals' Filemon to see what Im talking about.
NTFS flushes the write cache and updates its log journal. C$LogFile.
BTW sumone mentioned the ISO is blank, thats because its a 1.44 floppy image and will appear blank in windows. Just boot off it and it works fine.
I must say I didnt notice much difference enabling AAM - maybe you guys have better luck.
It would be nice to see before and after benchmarks to see how it affects performance.
I mean ideally, I would like my hard drive to be idle for hours until I shutdown, at which point it should spin up and write all the cached data. Notebooks have battery backup so Im not concerned about losing data. I think this is a big oversite and am considering switching to FAT32 for my system partition.
