High quality writing
and is the highest quality.
We have yet to see any conclusive evidence that the Plextor drives produce higher quality burns than anything else. In fact, the plex Premium is pruducing as much as 2x the C1 error rate on typical media than the LiteOn 52x, (hovever this may be related to differing error-reporting and measurement tools). No question that the Plex has a great package of gimmick features and software, so obviously there is some added value. As to durability, the Plex drives have been around long enough to earn that reputation, but so may the others, in time. But with current advances in technology, how long does a drive really need to last? will it outlast 2 or 3 LiteOn drives? What Plex has, more than anything else, is a reputation. And that reputation costs money. You have to decide for yourself if that's worth the extra price.
