Issue Details

I am currently writing data to a CSV file within LabVIEW but I am currently having performance issues and I am missing data when I attempt to acquire and log data at higher rates. What file format would be a better option when logging data at higher rates? 

Solution

When acquiring data at higher rates and logging them to file, NI recommends using a TDMS file format (per The NI TDMS File Format) to increase your application's performance.
