Forgot to share this on the web last month, but here's an updated 2012 plot of the history of storage capacity per inflation adjusted dollar for magnetic and flash storage from 1980 to April 2012. There is a clear logistic growth curve for magnetic media showing its terminal decline in density per dollar, whereas flash media seems to show a logarithmically constant growth (I know, go figure!). Figures are for consumer devices in the US consumer market. Flash media is from Intel only.
