using netCDF for storing data from realtime source

[Dave Allured]

Netcdf is best for array data, usually on regularly spaced grids.

What is the shape, i.e. dimensionality, of your data?  Your 
description suggests that the data is streams of single values over 
time.  If so, I suspect that Netcdf is overly complicated and not 
very suitable for your work.

How about a plain text columnar or delimited format, with each line 
about as you described, and a few appropriate header lines in each 
file?  Nothing beats plain ascii text for portability.
