NEC introduced its first dual 8x DVD recording drive ND-2510A, that supports beside 8x write speed for DVD-R and for DVD +R media as well as 4x write or rewrite with DVD-RW and DVD +RW media to write up to 8.5GB on the new double layer DVD+R9 media. Besides DVD recording, the drive writes CD-R media with 32x speed as well as Ultra-Speed CD-RW discs at 16x. The read speed of 12x for DVD-ROM and 40x for CD-ROM in combination with the access time of 140 ms for DVD and 120ms for CD comprise the most important 9 optical storage functions in 1 drive – the ideal all in one optical device.

As for the main features that differ the device from competitive solutions, they are NEC’s "high resolution writing strategy" and an improved version of NEC’s "Active Optimized Power Control" (Active OPC). The "high resolution writing strategy" uses advanced laser modulation to enhance the accuracy of the written data. Active OPC dynamically monitors writing power and reflection of the media in use, calculating the optimum laser power and adjusting it in real-time. Not only a media type itself is written in the optimum way – but even local anomaly on the used media can be handled in the optimum way by NEC technology. Besides, NEC implemented its own developed buffer under run error prevention technology.
