I would like to know the difference between GoodData project specific data storage and user specific data storage. I would also like to know their volatility and persistency.
You can read on Project specific and User specific data storage on our developer portal here:
Project specific:

User specific:
https://developer.gooddata.com/article/user-specific-storage
Note:
We preserve data 1 day on user stagging and 14 days on project stagging.
