If you're looking up records by a numeric primary key (which is most things in Drupal) or by some other properly indexed value, 500,000 records is nothing. A good RDBMS can handle millions of records. The keyspace for the primary key, if it's an integer, is somewhere around 3 million. Using an unsigned int or bigint will increase that even further.
Just use the Drupal file API. It puts the files on disk and the path in the files table, and should scale to hundreds of thousands of records just fine if you're using a recent version of MySQL.
