Are those the m-disc? I’ve heard they’re no longer using the inorganic layer you’re referring to, but still being sold with the same branding.

For me, it’s just too much risk. I don’t want to have to worry about counterfeit discs or a silent downgrade from the manufacturer. Those inorganic discs are slated to last a long time, but who really knows? A set of HDDs in RAID with a 3-2-1 backup strategy is the gold standard. HDDs do fail, and I’ve already planned for that.
You do point out some good points I didn’t consider before for BD-R, but for me, it’s NAS and sneakernet with flash drives for the homies. Hardly anyone I know has an optical drive anymore, much less a Blu-ray drive in their PC.
This is just Reddit falling for misinformation. That thread has been debunked so many times. There's a bunch of good YouTube videos covering it but long story short, redditors noticed something odd and immediately assumed it was some huge conspiracy when it wasn't.
And again, that 2018 paper... I encourage people to read it and see just how silly the methodology was.
Regarding the testing - Short of waiting 100 years, how else would you accelerate the degradation of the discs to simulate aging?
Not totally surprised about Reddit falling for some misunderstood labeling. Just curious about that, mainly.
However, even if they are perfect they still wouldn’t meet my needs. I couldn’t use them to share data with anyone I know, as nobody has a data Blu-ray drive. I can’t access the data on them at a whim, and they’re slower than a RAID array. I can’t easily perform automated routine data scrubbing to ensure corruption hasn’t occurred. Speaking of; how often do you verify the data on your discs, and how do you do it?
I can see its usefulness in some scenarios (cold storage), but I’m quite happy with my NAS.
I'm not sure, but I can say with certainty that increasing temps to 80C with 85% RH isn't any kind of demonstrable way of accurately predicting longevity under realistic conditions.
If I wanted to safety test a car, it would make sense to run a series of conventional car crashes. It wouldn't make sense to drive the car off a cliff and then claim that during testing, the car was proven to be unsafe.
I agree with a lot of other points. Personally, I just find it works better in my brain to have all media (TV shows, eBooks, movies, and music) organized on discs. Same goes with personal photos and videos. For certain things, I keep copies on my PC like photos and music, but for other things that I don't access frequently, I prefer to have them on discs. That said, I do have a HDD backup of everything. I'd love to get another large HDD but just can't justify the $$$.
