Why Microsoft and Warner Bros. Archived the Original 'Superman' Movie on a Futuristic Glass Disc
Microsoft has teamed up with Warner Bros. to store a copy of the 1978 movie "Superman" on a small glass disc about the size of a coaster. The collaboration, which will be officially unveiled at Microsoft's Ignite 2019 conference in Orlando, Florida Monday, is a first test case for a new storage technology that could eventually help safeguard Hollywood's movies and TV shows, as well as many other forms of data, for centuries to come.
"Glass has a very, very long lifetime," said Microsoft Research principal researcher Ant Rowstron in a recent conversation with Variety. "Thousands of years."

Microsoft began to investigate glass as a storage medium in 2016 in partnership with the University of Southampton Optoelectonics Research Centre. The goal of these efforts, dubbed "Project Silica," is to find a new storage medium optimized for what industry insiders like to call cold data — the type of data you likely won't need to access for months, years, or even decades. It's data that doesn't need to sit on a server, ready to be used 24/7, but that is kept in a vault, away from anything that could corrupt it.
This is not the Superman memory crystal we need.

With exabytes capacity, rewritability is no issue in normal use. Just write the replacement at a new position, followed by an updated directory. You'll not even come close to filling it during your lifetime.

It is useful at the terabytes level, which is what has been demonstrated (not by Microsoft).

I was replying to your last paragraph, where you explicitly mentioned exabytes, but conditioned on re-writability. My point is that at that size, for usual purposes re-writability of the medium doesn't matter.
