Jarrod,
Hi, thanks for the information on StreamStor I've contacted the company and requested information on their cards. Do their card integrate with Labview easily? I mean, will have to do lots of reprogramming? I've tested by Labview program with the process priority set to Real-Time and it appears that the data I'm capturing is correct. I have two versions of my software, one version I buffer up the data and then stream it to disk and the other version I stream it directly to disk. I have configured the incoming data to containg a 16-bit count that increments every 20-Mhz, therefore each recorded sample should be one value higher than the previous. I will be setting up my computer for a RAID disk to help stream the data faster. My final application will be to stream 32-bit data at 20-Mhz to disk. The customer may intend to record up to 20-minutes of data. I've only started with the 16-bit version to get a handle on Labview and later to upgrade to 32-bits.
My current computer is a 3.8Ghz Pentium with 4GB of Memory, if that makes a difference in the performance of my application.
One more question, do you see anything wrong with my program? The program starts recording data as soon as the user presses the Acquire button, is that a good way to start the recording processing? I've read another newsgroup post and another person who was developing a recorder mention used a Event Structure. I'm new to Event Structures, should I use one to start my recording?
thanks,
joe

Hi Joe,
I am afraid that I am not familiar with a specific company that does the same sort of thing as Conduant, but we have many Alliance members in our directory at ni.com/alliance.
To answer the previous post, your program looks good for what you are doing. If you are happy with the program starting as soon as the user clicks run and then entering in a file, there is no need to use an event structure. You could use an event structure if you wanted a separate button on your front panel to start the acquisition.
Let us know if you have any more questions.
Thanks,
Laura
