Forget pneumatics, they would not work as you expect for this kind of application.

An alternative if the load is light enough - say a magic marker - is to use a stepper with some Gates toothed belt and sprockets. That could be made to work pretty darned fast with a decent stepper. 0.1-0.5" is not a problem with either a lead screw or belt drive.
