using TDM VI in Lv 7.1 to stream data to disk

I found the TDM VI and the structure of the data is very interesting for my application. <br>I try to use it to stream an array of waveform data but the TDM VI goes very slow. <br>after that, I see in the documentation that TDM file can't support streaming to disk, but I think it's really a basic function. <br>futhermore,the TDM VI write binary data, so normally it must work !. <br>is there another possibily with TDM file to stream data to disk ? <br><br>Thanks in advance for your help. <br><br>GHELEYNS Nicolas<br>Phix Industries s.a.

For streaming applications as well as storing TDM files in real-time applications You should try the new TDM Header Writer VIs.
 
They allow You to use traditional LabVIEW functions to create a binary data file. Once the file has been created You only need to create an additional TDM Header file that describes Your binary file.
 
More information and a download you will find when You go to ni.com and search for "TDM Header Writer".
