To improve the copying speed from SD to USB?

Hi,

Processor : STM32f429

Frequency :180 Mhz

FatFs : Chan

In my project, I am copying the files from the SD card to the USB stick.

I having the problem with copying speed. Currently a 45 MB file copies in 1.55 minutes.

How to improve Speed? What are the parameters I need to look for?

The reading & write buffer size is 4096.

I have modified the Read buffer size for 512 to 4096. I had seen some files are corrupted while changing the read array buffer size.

Thank you.

Param.
