Very slow write speeds on arduino giga

[MoveElectricMobility]

I would like someone to increase the usb speed to full 2.0 speeds. right now I'm trying to write 187KB of binary data to a binary file using binary write mode in one single fwrite operation and its taking about 3 seconds. that is way too slow for the interface the board has.

Here is the code that should be running much faster:

error = fwrite(&write_buffer, sizeof(struct DATA_FRAME_RETURN), write_buffer_item_count, binary_file);

write buffer is an array of size 125, DATA_FRAME_RETURN is about 1500 bytes long, write buffer item count is 125, binary_file is a .bin file opened in the following way:

binary_file = fopen("/DRONEDATA/data.bin", "wb");

Any ideas? Any changes you guys can make to run the USB port at full speed? Thanks! :)

Just some follow up information, no matter how much data I send, big or small there seems to be a limit of near/equal to 500,000 bits per second. Is this a number set in this library or a property of the Arduino giga hardware?
