The question assumes that the data handling capacity is a
property of the software alone, which is nonsense. It is partly
a property of the software, partly of what you want to do with
the records, but mostly of the system on which it is run.

Try handling 100 million records with SAS (or anything else) on a
486 and see how easily it does it.
More seriously, the consensus is that on the same modern system
SAS is usually better able to handle large, dumb calculations
than S-PLUS, which is (generally) better than R. Horses for
courses.
