Report: 60TB disk drives could be a reality in 2016

It says that the largest drive now shipped in 2011 at 4TB and "From 2011 to 2016, the five-year compound annual growth rate for hard drive drive areal densities will be equivalent to 19 percent…" Doing the math, that brings us close to 10TB in 2016. How do we get from there to 60TB? At that rate of growth, we're looking at 10 years beyond 2016.

I have seen these 4TB drives offered for sale, but thus far, 3TB hard drives seem to be a better bargain in terms of dollars per storage capacity.
The description given would seem to imply a capacity in excess of 5TB. Is the drive rated at 4TB because some of the nominal capacity is actually used for parity checking, etc., as a means of transparently correcting data that are retrieved for the user? It would be nice to know, for example, that the drive could be expected to accurately maintain, retrieve and update its data without failure for a very long time.

Apple better have a successor to HFS+ that handles data integrity because the larger the drive the more potential for data corruption.
