As far as i know it wont really help to turn it off other than to stop your hard drive being thrashed when youre not using it. I suppose it would also help for when you just sit down at your computer, because it would be indexing and your hard drives wouldnt have to stop indexing and do what you need them to.

I turned mine off on my laptop but only because I hated the clicking sound when it was idle.
