My reference is data from particle physics experiments. These tend to go 
to extremes in terms of the number of data points. The big detectors 
easily create 1e6 values per shot at MHz rate. Still, they tend to save 
their data in ascii format. 
(e.g. http://lmu.web.psi.ch/facilities/software/general/psi_format.txt)

Since generations of particle physics projects have worked with this 
format, there is a load of utilities and tools.
(e.g. http://lmu.web.psi.ch/facilities/software.html)
This includes one of the most powerful data analysis libraries available 
(paw/minuit, which is GPLed)

A bridge to this continent of data analysis would provide more 
scalability than a spice application will ever need. The limitation of 
the CERN utilities is somewhere in the multi Peta Byte range.
