The authors reach the following conclusions:


1.      Economic sustainability presents the major challenge for long term digital storage. Paper survives benign neglect fairly well while digital information does not

2.      The rapid decline in cost per bit of storage will slow and may actually stop

3.      Long term cost of digital storage will become more difficult to predict

4.      The importance of developing improved digital storage cost models will grow

5.      For much of this decade tape is likely to improve its existing cost advantage over disk

6.      Improved cost models that properly recognize long term total cost of ownership (with respect to digital storage) will allow organizations to better exploit current low interest rates. Investment in solid state technologies, which despite their high capital costs, are for this decade likely to provide lower total cost of ownership than disk while retaining rapid access

7.      The pricing models of current commercial cloud storage services are not suitable for long-term storage
