The ND-3520A will write to DVD+/-R media at 16x, DVD+R Dual Layer discs at 4x, DVD+RW media at 8x and DVD-RW discs at 6x. The big news here is, of course, the performance boost in the RW space. Unfortunately I was unable to obtain any 6x DVD-RW or 8x DVD+RW media, although Verbatim informed me that this media will be available soon
