The cable is permanently connected to the NAS drive and is used to connect a temporary 2.5 "-HDD. In this function all faults and folds problem-free. Even with large amounts of data, there are no dropouts or transmission dips. The cable itself is well made. The plugs are clean (with no burrs and edges), the kink protection fulfills its function. The cable itself is a little stubborn, but still flexible enough. I would buy it again :)
