Using a filesystem the OS will write data to buffer before writing to a real device.  This is not a problem with a HDD or other storage media mounted directly on the camera, but with NFS mounted folder this causes trouble as the NFS driver will fill up the buffer and only send data over the network once the buffer is full - this causes a short hang on the camera and frames might be lost.
