SD Write Speed

Hello,

What is the max write speed for SD cards on the ChipworkX module?

I am using firmware version 4.1.4.0.

I tested the speed of the SD card using the following code.



private void someFunction()
{
string pathfile = "";
FileStream fStream = null;

LargeBuffer lb=new LargeBuffer(4000000);

pathfile=VolumeInfo.GetVolumes()[0].RootDirectory+"\\"+"Test.dat";


fStream=new FileStream(pathfile,FileMode.CreateNew);
fStream.Write(lb.Bytes,0,lb.Bytes.Length);
fStream.Close();

return;

}

Running this code I get 44kbytes per second.
Is there something I can do to increase the speed?
