so theoretical limit.. is what, and when exactly?
When talking about theoretical limits for data storage, I'm thinking about storage on a molecular level. You can't store much more than 1 bit per molecule. The closest thing I could find was
215 PB in 1 gram of DNA, which is still several orders of magnitude more than current storage systems.
We have not shown any signs of being close to the theoretical limit but we are slowing down.
Is that because of technical limits, or because newer storage types focus more on access time than size?
