Which SPI FLASH library to use?

Projects General Guidance

Hi,

I need to store sensor data to external FLASH. Roughly 50 characters per entry/line and up to 10,000 entries/lines.

Which SPI FLASH library would be best suited for this purpose?
For example I have found libraries below, but maybe there are others...
Preferably the library should work with ATSAMD21 and with ESP32.

GitHub - PaulStoffregen/SerialFlash: Library for using SPI Flash memory with a filesystem-like interface

GitHub - sparkfun/SparkFun_SPI_SerialFlash_Arduino_Library: A low level library for interfacing to serial flash ICs.

Thanks,
Tipo

Do you know what SPI chip(s) you will be using?

I have not set for any chip yet. If I find otherwise suitable library, I'm willing to try chips it supports.
