Airbus use baggage containers - and yes, you would usually know which container a specific bag is in. So once that container is offloaded, which shouldn't take too long, you have to find the bag in the container. Same for the A 380 as for your A 320, A 330 or whatever.
BTW: Airbus' official view on this can be found
here in their "Airport Planning Manual". so in an ideal airbus world, you'll have a 90 min turnaround. Yikes!
