Hi

When accessing Flash, you could tell me the read speed and write speed?

Thanks

From the STM32F411 datasheet, the maximum flash access speed is 100 MHz. You can refer to platform_config.h to check the PLL settings for flash clock speed as well as internal flash wait state.

I believe this information should be available in the flash datasheet.
