If you use partitioned views with CHECK constraints on the tables, your
performance will actually be pretty good. We store about 4 million
rows of data a day, and we keep a partioned view of about 90 days worth
of data; works fine, as long as you supply the appropriated check
constraint to the view when searching. Another benefit is that the
partioned view can be used to UPDATE and INSERT data.

There are some gotcha's (like passing a parameter to the constraint),
but for the most part, partitioned views sound like the solution.
