How to log image data acquired by imaqtool to disk with repeated triggers.

Here's an example code from the documentation, which waits for 100 triggers and acquires 5 frames for each trigger. I wonder how to log the image data into disk during the acquisition? I know we can get all data after the acqusition, such as data = getdata(vid,nFrames). However if the acqusition is long, it may run out of the memory, right? How to log image data into disk during the acquisition with repeated triggers?
% Create video input object.
vid = videoinput('dcam',1,'Y8_1024x768')
% Set video input object properties for this application.
vid.TriggerRepeat = 100;
vid.FramesPerTrigger = 5;
% Set value of a video source object property.
vid_src = getselectedsource(vid);
vid_src.Tag = 'motion detection setup';
% Create a figure window.
figure;
% Start acquiring frames.
start(vid)
% Calculate difference image and display it.
while(vid.FramesAvailable >= 2)
data = getdata(vid,2);
diff_im = imabsdiff(data(:,:,:,1),data(:,:,:,2));
imshow(diff_im);
drawnow % update figure window
end
stop(vid)

Hi Yuhan,
You can try setting the LoggingMode property as 'disk'. Refer to LoggingMode property documentation.
Here is the example with disk logging.
