What will we actually do with these cost figures?

Calculating the storage costs in relation to the archive costs allows us to look clearly at the measures which have to be taken to judge the quality or the continuity of the archive and to determine the importance of the effects of the measurements.

If we estimate, that in the coming decades we will have to deal with a decreasing margin between budget and cost, the following question could arise:

$ Should the storage costs per hour, which are dependent on housing costs in the long term:

* be increased.
* be decreased.
* stay the same.

If we make the above mentioned estimate, we come to the decision that the storage costs should be decreased. In other words:

$ The number of hours of information per cubic metre housing should be increased.
