Largest one I've used/test to capacity was 400GB, on multiple STM32 platforms (F4, L4, F7, H7..), and with FatFs builds that work properly..

Could probably get the F1 to work if I could find one with an SDIO interface, as the SPI is slowww..

This depends on the firmware (like FatFS), not the controller.

Any type with SPI will do.

Can i use SDIO/MMC interface and SPI interface irrespective of firmware? Or using which interface is suitable for large memory?

Any official tutorial from STM on how to write firmware to access SD card using SPI?

I found this one, however it uses SDIO.
