Hard drives fail in a few years. Factory printed dvd blue rays and burned M disc dont fail, right? So, you just by new and larger hard drives every 10 years?

Looks like physical media has a role.

I stored a cd R in a closet since 2004. It was sandwiched in a book for 2 years. I got curious and read it. All the files were there perfect. I copied the information and burned it to a Mdisc blue ray. In the mean time, I lost several gigs over the years from hard drive failures. One was internal of a laptop. Very unexpected. Another was an external harddrive.
