The distance vs. time that the electrons move (drift velocity) is dependent on the current.
More current = faster movement of the electrons but still very slow.
"Relation between Drift Velocity and Current Density
We can define current density as the total amount of current passing through a unit cross-sectional conductor in unit time. From drift velocity, we know the formula for drift velocity as:
I = nAvQ
J = I/A = nVQ
Where,
J is the current density measured in Amperes per square meter
v is the drift velocity of the electrons
Thus, we can say that the drift velocity of the electrons and their current density are directly proportional to each other. Also, when the electric field intensity increases, the drift velocity increases and the current flowing through the conductor also increases."
