NEC's latest addition to the market is the NEC-ND 3540A and as one can see from the specs in the table below, not many things have changed since the previous model, the 3530A. DVD±R burning speed is maxed out, so, no changes there. DVD±RW burning speed remains the same. So what does the new NEC model have to offer? Well, NEC has moved a step forward and much like all latest models, has introduced 8X +R DL burning speed. So, the ND-3540A is a 16/16X DVD±R recorder, supporting up to 8X/6X DVD+/-RW burning speeds respectively and up to 8X for DVD+R DL and 4X for DVD-R DL media.
