Maybe but i just installed voyager fresh and its 53mb. It was 2.6gb and if it only works when storage is low then it would get to like 65gb (thats what i have free) and with 2.6gb it was getting reeeaaaallllyyy slow. Now its fast again. So the theory sounds nice, in practice its not very much. Plus a big cache is nice when i need te revisit the same thing multiple times and it saves on time but since i dont really revisit things a lot its just a wast of space (my explanation is somewhat shit but hey, new years and booze)
