Why is Flash Storage (fstorage) and Flash Data Storage (FDS) still marked as experimental in the SDK 15.2.0 documentation?

Hello Nordic,

As the subject states, why are these two modules still experimental? From what I can see, they were introduced as early as SDK 10.0.0 which was at least 3 years ago. Is this a typo or is the documentation correct?

If they are still considered "experimental", what internal flash library/driver should I use that isn't experimental since pstorage has been removed in the latest SDK's?

Latest SDK documentation: https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/index 

Thanks!

Hi Derek, 

the documentation is correct, the FDS and fstorage modules are still labeled as experimental due to lacking due test coverage for some usage scenarios. The modules still go through extensive testing prior to releases and  the way the libraries are used in the SDK examples can be considered production ready. 

Hence, we do recommend using  FDS /fstorage as these modules have steadily been improved and bug-fixed since its introduction in SDK v10.0.0.

I have reported this internally and asked that the documentation is updated to state which functionality that is considered production and which is not. 

Best regards

Bjørn
