We study the flux flow state in superconducting materials characterized by rather strong intrinsic
pinning, such as Nb, NbN, and nanostructured Al thin films, in which we drag the superconducting
dissipative state into the normal state by current biasing. We modify the vortex pinning strength
either by ion irradiation, by tuning the measuring temperature or by including artificial pinning
centers. We measure critical flux flow voltages for all materials and the same effect is observed:
switching to low flux flow dissipations at low fields for an intermediate pinning regime. This
mechanism offers a way to additionally promote the stability of the superconducting state.
