A "cassette" type gearbox is a gearbox which can be removed and installed as a unit, without having to pull the engine apart. Just think of it as a cassette tape in a video cassette recorder, or stereo.
Its only real advantage is in racing, where you can have a couple of gearboxes, with different ratios in each one. With a cassette type gearbox, you can then change all of the ratios in the gearbox very quickly - just pull out the gearbox and insert another gearbox with different ratios in it.
It's only a better gearbox in that internal ratios can be changed quickly, if you have a couple of gearboxes. It may not actually be a better gearbox, as such.
