There's a class boost::array that will sometimes meet your requirements.
There's another proposed class that will probably show up in a future
version of Boost called boost::fixed_capacity_vector that might also meet
your requirements. A boost::scoped_array or boost::shared_array is
occasionally useful, but not often.

But be wary of overestimating the importance of std::vector's low overhead.
It's often quite affordable, and not having a fixed capacity limit can be a
valuable feature that can help you avoid buffer overrun problems.
