Your welcome. Tbh we will never know if the media will ever live 1k years, I doubt it imo, but considering it I think it would easily withstand at least one life time if well stored. And even in non optimal storage the thing can resist to a lot of damage. If you go read the laboratory stress test please read the whole documents and what kind of stress it is. A lot of people do read them and say "but it failed the test" .
