So far I have tried:
(Burned without problems, second USB cable I connected with in all cases) Several videos in Full HD burned to Blu Ray blanks
Fired several videos in SD resolution to DVD Media (burned without problems, second USB cable I connected with in all cases)
Audio CD burning (burned without problems, second USB cable I connected with in all cases)
The videos were super read with VLC Player. The drive worked quietly (maybe it's up to the rubber feet I do not know myself ?, because of :))
