Increase Data Availability for Important Blocks

Question:
How can I increase the data availability for important blocks?
Answer:
For data which is highly necessary for the application, use redundant blocks with CRC. This increases the data availability and in case of a write error or abortion, a second instance is available.

For data with high impact, the loss of the latest version is not acceptable and no redundancy combined with default data is sufficient. Mark this data block as critical. Critical data blocks are secure even in case of frequent resets. But take care, with every data block configured as critical, the Fee performance and flash lifetime decreases (only single sector usage).

The option Critical is only available in Standard Fee.
