I get only 25 kb/s transfer speed from TWR-K70 (full speed usb module used) to 2GB Flash stick (FAT32, 512 b allocation unit). Several different sticks used.
My program is derived from msd_mfs_generic_test - no changes made to the project, only transfer speed benchmark added to it.
The transfer speed is measured at disk_write() function - its takes 20 ms to execute it. Every call writes one sector (512) so the transfer speed is 25 kb/s.
I have no clue how to speed it up...
