TrustedReviews posted a review of the HP dvd640i LightScribe DVD Writer
First things first, this is a very slow DVD writer, at least it is by modern standards. In fact it’s been many months since I’ve seen test results as slow as those turned in by the HP dvd640i, but this drive isn’t about raw performance. In fact, despite it’s undoubtedly tardy behaviour it has one trick up it’s sleeve that no other DVD writer I’ve reviewed has exhibited – LightScribe functionality.HP dvd640i LightScribe DVD Writer
