Narrative:

Scheduled to operate in an aircraft with some questionable deferrals. I expressed my concerns to the duty chief pilot; dispatcher; and maintenance. Upon raising the landing gear after takeoff; using ldg gear warn sys 2; received ECAM warning message of: gear system 2 fault. Followed ECAM and switched to sys 1; thought it would be ok; above 10;000 MSL while accelerating to climb speed; received gear warning overspeed message. Both pfds displayed red zipper and ECAM had overspeed warning message. Was in conference with dispatch and maintenance immediately following; and consensus was this is not how the system should be working. Lost direct contact with dispatch via radio (weren't able to use ACARS at all-deferred prior to block out); received message from ARTCC to return to the departure airport. Didn't declare an emergency; because it appeared the gear was retracted and would have in the event we didn't receive a gear green down and locked; which we did. Landed uneventfully.
