Minimal Long-Term Storage Economic Model

A minimal model of the endowment needed to store one terabyte on disk "forever" under a set of assumptions which can be adjusted. It is an initial, greatly simplified version of earlier work by the LOCKSS Program and students at the Storage Systems Research Center of UC Santa Cruz. This work was published here in 2012 and in later papers (see here).

The endowment is the money which, deposited with the data and invested at interest, suffices to pay for the storage of (in this case) a terabyte "forever", which in this model is 100 years.
