Product-specific answers based on available technical information.
NI specifies 64 MB total, implemented as two 32 MB memory modules.
The specification lists 20 MHz for small transfers and defines a small transfer as the FIFO size. This is not an unconditional sustained-transfer specification.
NI documents programming support through NI-DAQmx and Traditional NI-DAQ (Legacy). Check the specific driver release and operating system; historical support does not establish support in every later release.
