Is there any way to to tell Finder to default to moving rather than copying files from my main system disk to another disk?
My main system disk is too small and I have a secondary 'main' disk which I use for media, larger files and the like. I know I can hold down Command to change the behaviour transfer by transfer, but sometimes I forget or hit the wrong key or Finder just decides it'll do a copy anyway. Move, rather than copy, is almost always what I want when transferring files between these two disks so that would be a better default for me.

As far as I am concerned, there is no way to change the default behaviour.
Keyboard
Make your selection in Finder and hit CMD+C. Open the target folder and hit CMD+Alt+V and Finder will move the files to your desired location.
Mouse
Hold CMD while you drop your selection to the target folder. Mac OSX will then move the files instead of copying.
Personally, I prefer using the keyboard when moving around large selections.
