NEC ND-3540A
NEC is quick to update its writers, even if the change is limited to increasing the writing speeds, and the ND-3540A achieves the highest speeds currently available. NEC is one of the major manufacturers of chipsets for DVD writers, so logically, they've used their own in the ND-3540A.

The NEC's write-failure protection system is called WOPC (Walking Optimal Power Control). It controls the quality of the medium at the beginning of the burn, but also throughout the process, allowing the writing speed to be optimized for the temperature of the medium. There's also a system for suspending the write process if the writer's buffer memory empties.
