Why not? It takes less than a second at boot, and then it's available immediately without having to spin up again.

The gain is getting voice immediately when you enter the menu, without having to wait several seconds for the disk to first spin up and then load the file.

My point is why not read the whole voice file at that point? The disk is already spinning, so it will only take a second. Waiting until the voice is actually needed means having to spin up again, thus spending several extra seconds waiting.
