Moore's Law actually predicted a doubling every two years (for CPUs), not every year, and even the very optimistic Kryder's Law (often cited as the version of Moore's Law for storage) only claimed an increase of 40% per year. Actual progress has fallen far short of that. The rate for 2010-2014 was only 15%/year.

Rates were quicker back around 2000-2005, but that pace has fallen dramatically.
