SDIO + DMA on stm32f103

Hi everyone,

I am using SDIO interface to write to SD card without using DMA. I am writing about 300 bytes of data at 50Hz. The problem is that with current implementation it slows down the code.Thats why I am thinking of using DMA for the data transfer to eliminate this issue. 
Now, I have 2 questions:
1. Will using DMA with SDIO help enough to allow writing 300bytes at 50 Hz.
2. If it helps, Can someone provide me a sample code of this usage. Otherwise, guide me in the right direction for implementing the same.

Thanks
