Why does my MBP access the hard drive so much more in Windows 7?

[kuykee]

When I'm booted in OS X I hardly ever hear the hard drive clicking or reading information off the disk directly after booting. But when booting into Windows 7 the hard drive clicks and reads and makes noise a lot more often.

Is this something to do with the design of Windows? Like... the way data is organised on an NTFS disk/fragmentation etc? I run Defraggler pretty often, although often in Quick Defrag mode.

Anyway, it was just a question, and probably a matter of operating system resource efficiency right? I.e. OS X is somehow more 'efficient' or loads crucial system files into RAM somehow better? I'm not sure, just speculating

What do you guys think/know/speculate?

Windows does run defragmentation in the background, but not continuously.

Anyways I find Windows to be more efficient than OS X. The former usually feels a lot faster in every application I use.

You can reduce a lot of the drive access by disabling drive indexing. This is the most likely culprit. You can also turn off defrag scheduling, and just run it when you need it.
