Sam,

The transfer rate of the NI PC-DIO-24 card is dependant on a variety of factors. According to the documentation the maximum transfer rate is 50 kbytes/s with a constant sustainable rate of 1 to 10 kbytes/s (using NI-DAQ software). Some influential factors include computer system performance, programming environment, execution mode, and the presence of other processes running concurrently on the system. (see NI PC-DIO-24 User Manual)

I would recommend using NI-DAQ if you are not already doing so. The NI-DAQ drivers are free on our website and can be downloaded at NI-DAQ 7.1 for Windows 2000
