Reading performance:
For these tests we will use Nero CD/DVD-Speed to read various CD and DVD's, including audio discs and DVD-media. As already mentioned in the introduction, this drive supports:
- DVD-ROM : 16x
- CD-ROM : 48x
Pressed discs:
For this test we used a pressed CD-ROM disc containing Creative Blaster Audigy install CD that is close to 74 minutes long. Below you will see the produced result:
The NEC ND-4550A reached 45.99x. Let's compare the result in the table below:

Again the NEC ND-4550A performed average on the CD-R read test.
* Some drives including the NU HDW-164 will simply execute the seek command without actually moving the pickup.
CD-Rewritable discs:
Again, we made a copy of the original Creative Blaster Audigy install CD; this time we used a Verbatim Ultra Speed (32X) CD-RW disc made by Mitsubishi Chemicals Corporation.
As we can see above, the NEC ND-4550A is locked at 40x, reading CD-RW; now let us compare it to other drives below.

* Some drives including the NU HDW-164 will simply execute the seek command without actually moving the pickup.
Audio - Digital Audio Extraction:
We used Nero CD/DVD-Speed to measure the transfer rate. The audio disc we used is slightly larger than the disc used for the other tests, to be exact it's about 78 minutes long (77:43:45).
The NEC ND-4550A is locked at 40x while reading CD-DA discs. Let us compare the result with other drives:

The NEC ND-4550A performed average on the Audio-CD test.
* Some drives including the NU HDW-164 will simply execute the seek command without actually moving the pickup.
|
And as a last test we used Exact Audio Copy (EAC) to extract the audio to our hard drive. According to EAC the NEC drive does not support Caching, which is considered as a plus - while ripping audio. |
|
Below is the results produced by EAC:
Burst mode
Secure mode
The drive performed well in burst and slower in secure mode.
Advanced audio - DAE quality test:
Before we move on to testing DVD read speeds, we will take a last audio test, and this time we used the 'Advanced DAE Quality Test" feature in CD-Speed. For this test we used a CD-R DA media from MMORE (Thanks to MMORE (NL) for sending us this media).
The extracting quality is excellent and it should support everything, except reading the Leadin / Leadout.
DVD reading performance:
Again, we will use Nero CD-Speed to measure the reading performance, this time for various types of DVD discs. The drive should read pressed single layer DVD-discs at 16X.
DVD - DVD-Video:
For our DVD reading performance tests we are going to start with a single and Double Layered DVD video discs. While only 1X speed is required to watch DVD movies, it's useful to be able to read the discs at higher speeds if you're going to extract (rip) the content of the disc to your hard drive.
DVD-Video Single Layer
DVD-Video Double Layer
As we can see the drive reached 16x on DVD-Video Single Layer and 12x on DVD-Video Double layer.

Once again the NEC ND-4550A is among the fastest drives reading DVD-R and DVD-RW.
Overall thoughts:
The NEC ND-4550A is a very good reader.
But now it's time to head on to a more interesting part: Writing CD-R and CD-RW discs…
