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?
