This is a most excellent place for technology news and articles.
Data on hard drives also generally lasts a long time. Much longer than 5-10 years.

Rated for, but that doesn't mean they're all actually manufactured to that standard.

That doesn't mean all M-Disc manufacturing is immune to shitty business practices of a manufacturer, but they do have to meet certain manufacturing specifications.
