Only use consumer SanDisc or industrial Panasonic SLC (no longer manufactured) SD cards, all other brands are scams. The SD cards have peaked at 1TB but they are getting cheaper. (so far) Only use Intel SATA SSDs, I bought X25-E SLC drives from 2011 to get that 65nm 100.000 writes per bit. But yes, media will have to be replaced, as a whole with open-source software and distributed databases everything will be saved.

Now this leads to interesting question about media. Will SD interface be superseded for something else? Or might everything be in cloud or something. If the hardware works, but you can't get software there anymore how usable will it be.

  No, SD cards use flash memory which is based on quantum flips. There wont be anything substantially better per GB/W/durability/$ than 65nm SLC just like 28nm is pretty much the peak of transistor size advantages. The lower you go from 65nm the brittler it becomes, also smaller and that's how the flash MLC has reached 1TB on the same surface (micro SD) that only allowed 8GB SLC. My X25-E drives are only 64GB!!! Photon/Quantum processors will never match electrical in Gflops/W/durability/$. Magnetic drives are not an option because of energy consumption. Also with peak hydrocarbons we don't have the energy to keep growing development/building of new things: So yes your concern is valid, what happens if SD/SSD media explodes in price and eventually is unavailable? My answer is buy the media you can right now and plan for it's use, charge ALOT for writes! Don't log anything. And try to get SLC while it's still available to buy: I have calculated that for the 1 million customers I plan to have (I will cap my user base, but since the software in open-source others will hopefully fill the gaps if the product is successful) I have enough drive durability to store and update their records once per day for 500 years. Set a limit to what you want to do. Apply the same to monitors, keyboards, mouses, power supplies, cases (passively cooled), batteries (lead-acid), routers, switches, cables etc. If you play it right the glass in the fiber strand will need replacing before your hardware stack does. And it probably will get replaced for high latency / low bandwidth messages by P2P radio: http://radiomesh.org http://radiomesh.org

  I once soldered wires directly to the pads on a microSD to SD card adapter and, through a level shifter and managed to use my Arduino Uno to save text (GPS readouts) on microSD cards. I think even if more advanced storage comes along, SD cards will still be desirable for the simplicity and backwards compatibility.
