It isn’t writable
Comment on Indestructible quartz crystal can store 360TB of data for billions of years

They say “billions of years” but that sounds like just the sort of thing a stray cosmic ray would ruin.
Maybe they’re planning on using a checksum for error correction like they do with RAID.

So?

What would be the point? You would just know that the data is invalid. You couldn’t fix it

Use the checksum to correct the read, just like always. You don’t repair damaged ROM anyway.

On that timescale, what are the odds that the checksum is still reliable?

Why would it be any different from the real data? Checksumming is basically just writing extra copies with math.

I’m asking why it would be more reliable if it has the same vulnerability to being corrupted.

Checksums are redundancy.
