It is considered a best practice to use a 1:1:1 ratio for Disconnected Scanning workstations, scan queues and disk groups. By associating each Disconnected Scanning station with its own, unique scan queue and that scan queue with its own, unique disk group, you ensure that a backlog of pending and/or failed uploads will not be created by multiple Disconnected Scanning workstations attempting to upload batches to the same disk group.
