Not sure where you got the 20% number from,

There was a paper from Seagate, which I believe is referenced earlier in this thread, that said the technology provided a 25% improvement in areal density. I read somewhere else that there's a 5% overhead for something else - metadata or guard bands or something, bringing the effective improvement down to 20%.

If that's just a prototype figure and the technology eventually gets to 3-4 times areal density improvement, that's a different story.
