Expert Answer:

The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field.
 
In general, an electron will 'rattle around' in a conductor at the Fermi velocity randomly. An applied electric field will give this random motion a small net velocity in one direction.
