Nor memory QSPI efficient data logging

[vincent.golle]

Dear Nordic,

For my application I am now using a NOR memory with my nRF52840.

This memory needs the FAT file system as my device implements USB MSC and uses regular files.

My app needs to log data every second (about 20 bytes per write), and this logged data can amount to several MB in total before it is unloaded.

I have noticed that using a file in append mode in the NOR memory takes (very) long processing times... and can also crash the system !

My question is the following:

How an I efficiently store this data in my NOR flash memory using the nrf_qspi library ?
