Re: Permanent Storage
"My issue is that there isn't anything permanent to store data (write once, no degradation)"
Because you're chasing unicorns. NOTHING lasts for extremely long periods, especially if abused. Even stone can suffer erosion or crack to an earthquake, and diamonds are actually UNstable over geologic time (graphite is carbon's most stable form at STP). The best you can do is buy some time, the price rises with the length, and there are no real guarantees.
And over geologic time? The Kansas song "Dust in the Wind" springs to mind.
