I can get a 32GB USB thumb drive for $4 at my local Micro Center retail store and it’s rewritable. That’s a lot cheaper than throwing away BD-R media and it is much more environmentally responsible. it’s also much more rugged. If you set it down on a surface, you don’t have to worry that scratching it will render it unreadable.

Huh? USB sticks are designed to be inserted and removed with the power on, retaining data throughout. If they didn’t work reliably, people wouldn’t use them. I have flash drives with live OS images from which I can boot, and I’ve used some of those for months at a time for some projects. No problem.

Your Blu-Ray player boots from internal flash media! So does your AV receiver. So does your television.
Smartphones use flash storage for their OSs, apps, photos, videos, etc.
Digital cameras store their firmware and photos on flash storage.
Marine GPS chartplotters store their OS, navigation charts, sonar data, and GPS tracks on flash media.
Automotive GPS systems store their maps on flash media.
All personal computers low-level boot from flash storage, whether it’s the BIOS or EFI.
These are not devices that consumers turn off and find that they randomly never boot again.

I store my videos on RAID-6 NAS devices. Unlike videos on BD-R discs, those on my NASs can be read by any device on my network, whether it’s computers, tablets, phones, or media streaming devices (Amazon Fire TV Stick 4K, Apple TV 4K, Roku, etc.). And I don’t have to manually check them regularly for degradation, inserting and removing each one in turn.
