Reminds me of when I started working on storage systems as a young man and once suggested pre-computing every 4KB block once and just using pointers to the correct block as data is written, until someone pointed out that the number of unique 4KB blocks (2^32768) far exceeds the number of atoms in the universe.

It seems like you weren’t really that far off from implementing it, you just need a 4 KB pointer to point to the right block. And in fact, that is what all storage systems do!
