The guys at CD Freaks have taken a look at Samsung's new 18x "Super-Multi" drive, the SH-S182D. Here's a sample of what they had to say:
The total 18x DVD writing times are very good and the quality ok on this Samsung SH-S182D.

The CD-R write quality is excellent with the Samsung SH-S182D, with most tested CD-R media returning impressive results. Write performance was also impressive with many burns well under 3 minutes.
We too have a review of the SH-S182D in the works. In the mean time, head on over to CD Freaks and check out their review.
