Hey Justin,
I hate to admit it, but I still have a large stack of Betacam SP, Digital Betacam and HD-CAM + various DV, HDV and VHS tapes floating around under my bed, and in various boxes – and today, there is still not a cheaper storage format than tape, except when the emulsion paints the heads in the VTR…
I suspect that it will either be cloud based (AWS, Azure, Google etc) or SSD drives that wiull be the way forward. I did buy a stack of BlueRay blank discs, but not as solid as I would like it.
The alternative is to ditch the old source “files”, and just save the masters…
SORRY! That is not the right way to do it.
But many of the big brioadcasters did just that back in the 1990’s when there was not enough Betacam SP tapes in the world, and they have continued to do so when they moved to camera-cards.
Sorry, the above is not helpful.
However, even if not in your territory, can I suggest that you reach out to Peter Rowsell at Polar Graphics, who is based in the farm-country belt of London, UK. Apart from Peter having represented most of the known on-line, and near-online data-storage systems and software for the media business, he also knows alot of other stuff. And, might just help you connect a few missing dots to build something that will last you the 20-years.
Magstor is one of their products:

If you do catch up with Peter, please send him my best regards and let him know that I have not forgotten, neither ghosting him, just been busy. But my eternal gratitude to him remains intact. 🙂
Hope that this helps?
