@dbrgn The library may also have a local cache, which would be used for reading, and could compare values against the cache before actually writing to flash. There could also be some way to write only a few bytes rather than full sectors like a filesystem would do, not sure if that's actually possible with the flash interface used.

I do not know but it may depend on fw version. Also no idea whether stored data survives fw update or not. I'm missing methods get number of total/used indexes get list of keys Also there are some smaller issues with retrieving data with non existing keys, etc.

I like that idea.
