What is a good way to represent a collection of bits?

I have a set of various on/off toggles (thousands of them) and need to store and retrieve their state. The naïve implementation would be an array of booleans, but I'm wondering if there's a better way (better in terms of access speed and/or memory requirements).

I've found this BitArray implementation, but it's limited to 32 bits, which is not enough for this case.
