NEC ND-2510A

1. Retail Package - Installation

NEC ND-2510A Recorder - Page 1

After the big success of the ND-2500A drive, NEC released in June of 2004 the ND-2510A. The ND-2510A is able to write up to 8.5GB on the new double layer DVD+R9 media. This multispin drive supports both +R/+RW and -R/RW discs along with DVD+R9 discs at 2.4X. Although there are drives on sale that can record a full disc in less time than the ND-2510A, NEC's main interest is burning quality, and not so much the speed.

The ND-2510A takes advantage of NEC's "high resolution writing strategy" and an improved version of NEC's "Active Optimized Power Control" (Active OPC), the "high resolution writing strategy". NEC further includes its own buffer underrun error prevention technology.

- Features

The NEC ND-2510A can read at 12X max DVD-ROM discs and 40X max CD-ROM discs. It can write at 8X for both -R and +R DVD formats, and can write/rewrite at 4X -RW and +RW discs. The recording speed for DVD+R9 discs reaches 2.4X. As a CD recorder, it can record at 32X max when CD-R discs are used, and 16X max with CD-RW discs. Unfortunately, this drive does not support DVD-RAM media.

The drive does not support Mount Rainier and it uses the well known RPC II region control, allowing a user to change the drive's region at most 5 times. Below are the drive's main specs as given by NeroInfoTool, VSO Inspector and DVDInfoPro:

- The drive

The European retail package includes an installation guide. Also included is Nero 6 software for writing, InCD for packet writing, Nero Wave Editor for sound editing, NeroVision Express 2 and Nero Recode for authoring, Nero Showtime for DVD playback, Nero Digital (MPEG4), Nero BackIt Up and Nero Cover Designer..

The IDE cable, audio cable and mounting screws are also included.




We received one black colored and one white colored drive from NEC. You can see from the pictures above that the faceplates not only differ in color, but the DVD+R DL logo is shown only on the black colored drive. However, we removed the screws and covers from both drives and found that the the drives are 100% identical. Maybe all drives released from hereon will display the DVD+R DL.

On the rear panel you will find the analogue and digital audio outputs (SPDIF), the IDE slave/master selection pins, the IDE connector and the power input.

Removing the screws and opening the drive's cover voids the drive's warranty. For reference reasons, we post the following pictures. Click on the photos for an enlarged view.

The drive uses the same chipset as the ND-2500A, namely the D63630. Clicking on the image above will reveal a high resolution image. Notice that inside the ND-2510A, there is a white barcode label with 2500A written on it!

The following picture shows the laser lens of the ND-2510A . Clicking on the photo will open a higher resolution picture.

It should be noticed that the laser head unit of the ND-2510A is exactly the same as that of the ND-2500A drive! Clicking on the above image will show a high resolution picture. For comparison reasons, you can also see a picture of the ND-2500A laser lens here.

- Installation

The device was connected to our test PC and was identified as "NEC DVD_RW ND-2510A" under WinXP. All tests were done with firmware revision v2.15.

In this review, we will be comparing the drive with the LiteOn SOHW-832S since both drives have similar specifications.
