SQLite[0] might be worth a look, especially if you can split your data
across several instances of SQLite.

The key difference of SQLite to things like MySQL, PostgreSQL, and
others is that SQLite is not a server, in that it doesn't offer remote
access, which you say you don't need, so that is not an issue.

Additionally, you have no overhead of administering (or at least
setting up) a database server and its users, and SQLite is lighter on
your resources. ;)

If you have data that doesn't lend itself well to storing them in the
rather rigid confines of SQL, take a look at the NoSQL DBs like
CouchDB or MongoDB. All of those (and the SQL engines) have good to
great Ruby bindings, so you can use them with relative ease.
