I don't think so. FDS overhead is at least 12 bytes/record IIRC - yielding significanly more than 300KB flash usage. And since records need to be 4-byte aligned, the 25 bytes expand to 40byte/record.

Also finding a specific record would take a significant amount of time.

You could try combining your data records in larger structures for more efficient FDS memory usage, but - depending on how often you need to update - you might soon run out of flash erase/write cycles.

The internal flash space of nrf52832 is 512K，including 152K softdevice and 40K application，and the remaining 300K space is available.The 300K flash space should be enough.

I recommend using external SPI/I²C flash memory - you would not have enough internal flash space left for application and softdevice.
