And yes, it works fine, people have been doing it for years.
The media we use is some of the most quickly degrading stuff when you actually compare it to other stuff. Old archival footage survives better than HDDs. HDDs survive better than CDs/DVDs. Stone tablets last the longest, if you want real data integrity
