The NEC ND-3540A supports the DVD+R DL/-R DL standard for writing Double Layer discs with a size around 8.5 GB at a writing speed of 8x/6x. Let us first take a look at the media's we will use:

Let's find the manufacturer and media information too, for this we will use DVD Identifier 4.01:

The media is made by Ricoh Co. Ltd. (Made in Taiwan). Thanks to Ricoh Europe (Germany) for sending us this media.
Testing procedure: We created an ISO Image of the largest DVD-Video disc we had (Nemo, 7.91 GB (8.495.888.384 bytes)) using DVD-Decrypter. Then we wrote this image file using Nero Burning ROM 6. Below are the results:

Ricoh Media
Nero reported 'could not perform end of Disc-at-once, so we tried another disc:

Ricoh Media
Nero reported the same error again.

Traxdata media
Nero reported the same error on the Traxdata media too.

Verbatim media
The burn was successfully on the Verbatim media.
Let us take a look at the K-Probe result:

The reported errors in KProbe are probably due to the disk not being closed in the 'Disc-at-once" operation.

The result is excellent, considering this 2.4x certified media was written at 8x. Now it's time to take a look at some reading tests with various DVD-Writers.
First we will try to read the discs back in the NEC ND-3540A:

Ricoh Media

Traxdata media

Verbatim Media
As we could see, the NEC ND-3540A had no problems reading the disc. Let us try some other drives to read the Double Layer discs:

Ricoh Media

Traxdata media

Verbatim Media
The Plextor DVDR PX-712A had no problems reading the medias. Let's compare the NEC ND-3540A with other DL capable drives.

Again, we used Nero Burning Rom 6 to write the DVD Image:

The NEC ND-3540 used 20 minutes and 44 seconds to write the Verbatim DVD-R DL 4x media at 6x. Let us see how the quality is:

All DVD Standalone devices played the NEC ND-3540A burned DVD+R DL medias. But only one DVD Standalone devices would play the NEC ND-3540A burned DVD-R DL media
Summary: Very good quality on DVD+R DL/-R DL and DVD standalone compatibility results, for the DVD+R DL media.
Before we round off this review, let us run the drive through some advanced tests at next page…
