Excellent burner, one of the very best. Ok reader, but nothing special. For reading, there are better choices like Samsung and LiteOn drives.
But as far as burning is concerned, it doesn’t get much better than this. DVR-115/215s are rather hard to find these days though, since they’ve been replaced by the 116/216. If you can still find them, I’d definitely recommend the DVR-215 (SATA modell), have that drive myself.
