Saving memory to internal / external flash

Projects General Guidance

Hi everyone,

I think there was a misconception on my device. I am developing a wearable and thus cannot use a USB drive. It has to be stored on the device itself

I would need to write new data (steps, HR, and time) perhaps once a minute and read from it once a day (this will really depend).

The two options are using:

  • Microcontroller flash storage (I have plenty (about 200 KB spare))
  • External embedded flash chip such as the W25Q80DV

I am trying to determine what is the best decision based on efficiency, power, and good practice.
