Hi
I want to know if I can reach a writting speed of 3-4Mbytes/sec to MicroSD ?Microcontroller is STM32F103RET.Clock rate: 72MHz.MicroSD 2-4G calss 10.SDIO protocol.If you have any same experience , please to help me. #stm32f103ret-sdcard-sdio2016-08-12 10:23 AM
I think you're unlikely to achieve that level of performance in a sustained manner.
Writing is highly dependent on the card, the clocking speed of the interface, and the size and alignment of the blocks of data written.
