The default situation Take your Drupal Database and check what are the cache tables used, here I’ll use a quite basic default Drupal installation on Drupal6: And the answer is that a relational database provides more services, it can for example provide a better persitency, or manage better simultaneous writes, or allow handling relationship between dgupal.
