What version of LabVIEW and DAQ are you using? With LabVIEW 7.x, we greatly enhanced the effeciency of file writing. Also do write in binary, such as waveform data types.
Can you reduce the data prior to writing to file? 32 channels at 10k/second should not be a problem. With today's fast IDE drives I have seen 56 channels at 16k going to disk while the rest of the application (very processor intensive) is able to keep up. Preston Johnson
