I think we would all hoard data if it was cheap.
Today I had to suggest cloud storage. That’s the cheapest and easiest to maintain.
There is optical storage solutions that is adequate for most consumers and even LTO tapes it is fast enough, can be produced cheaply but the drives are advertised to businesses and sold with that business premium cost.
This bugs me. Also the fear of being deported soon

It’s not hoarding. It’s securing. Cloud services can’t be trusted to be secure and available in the long term, some of them not even in the short term. They are capricious and arbitrary in their unilateral termination of service without notice.
Average punters can’t be trusted either.
Whenever I go to my family’s houses to check the NAS’s, they are often turned off (or not turned back on after a power outage, or having been unplugged).
I would love to roll out some integrated, but modular solution with RAID, UPS, remote synchronisation and reporting, that doesn’t require a 19” rack.
Unfortunately, the rest of my family barely comprehend the need for a reliable backup, let-alone data sovereignty.
What about a 10 inch rack? Jeff geerling has a few good videos on Nas solutions in a 10 inch rack
