A storage system (1) has a chamber (3). In the chamber (3), multiple storage tanks (5) are arranged, and a picking and placing device (8) is arranged above these tanks. Carrousels (8) are arranged in the storage tanks. These carrousels are suspended from a top pivot bearing (35) and laterally guided by a bottom pivot bearing (44). The top pivot bearing (35) is located outside the insulation (12) of the storage tanks and is thus protected from extreme temperatures. In the carrousel (18), storage cassettes (20) are arranged which are laterally held by guide elements (31).
