If you want functionality, the LiteOn LH-18A1X series are your best bet.
Jitter measurement, TE/FE scans (?), HyperTuning learning mode, Online HyperTuning, third-party firmware support and so on :bigsmile:
If you don't want LiteOn, you should go for the NEC, as it also has third-party firmware support (from Liggy and Dee). Kudos to L&D for their excellent work, btw
Samsung burners are like poor forgotten bastard children, they don't nearly have as much support while they are also Mediatek chipset-based.
NEC and LiteOn (7S series) have also introduced SATA burners although the particular models are few and far between. It may be better to look for those if you need SATA.
