If you care about local data preservation and you’re storing remuxes you should probably be storing them on a nas, or really just on a raid array. This allows for error correction due to the parity stripes and everything, and provided tolerance for drive failure.
If you were really serious about it, you’d want a mirrored nas offsite, or you’d push encrypted backups to cloud storage or something. But if you care about storing data as long term as possible you absolutely should not be storing the stuff on a single ssd or external drive or anything.






Nothing really, but the lifespan of burned BD’s could mean you don’t have access to your data in the future.
