Comment on M-DISC – DVD/Blu-ray compatible discs that may last up to 1000 years

Comments

When you die your kids are going to throw most of your stuff in the bin. Those discs especially.

I've burned our home movies etc onto Bluray (BDMV) precisely because I think it's the easiest way to preserve these memories in a self a documenting way.

What has a greater chance of being watched in the future? A disc labeled "Home Movies 2020-2022" that conforms to a wells documenting standard (even if it is obsolete in the future), versus a folder on a NAS that can only be accessed over SMB, or an account on a cloud storage service whose terms and authentication method may change without notice?

I'd be willing to bet that the longevity and accessibility of the former outweighs the latter. All of these approaches require ongoing maintenance: the latter methods require maintenance against an environment that is actively changing and not self a documenting.

I don't think we should underestimate the power of a physical object that can be inspected and transferred by anyone capable of manipulating and observing the world.
