I'm trying to read SD card using Mass Storage Protocol via STM32F746-DISCO board. I found example in Applications\USB_Device\MSC_Standalone which does exaclty what I need. However the read/write speed is bad. It's about ~300kB/s. I'm reading FAT 1GB SD card. Is there any way to do it faster? This evaluation board uses 4-bit SDMMC1 interface to communicate with SD. USB HS is used to act as MSP.
