  Facebook uses both among others.

For development/testing purpose, updated schema is enough; up-to-date data is not required.

  That's sufficient for some kinds of testing. It's not sufficient for performance testing or testing for changes in user behavior.

    I don't know. We use artificially populated data for performance testing. for user behaviour and other metrics, they would have programs running against the actual production database, not a stale developer copy of it.
