Hi, I created an application that write on sd card, but i need to write the sd in high speed (at least 4MB/s). I used the library diskio.c, and the program run and write, but actually i write 5MB in 40s. It's too bad for me, do you have any suggest?

Your SD Card write speed depends on several things, including the type of SD Card itself. So the first thing you can do is get a 'fast' SD Card. A quick google search turned up several posts that might be helpful:
