(Optimus Prime and Megatron not included)
The ND-4550A we received from NEC was an OEM version. The drive did not come with any software, cables or even a printed manual.
Physical Features:
The drive NEC sent us for this review was manufactured in August of 2005 and had firmware 1.06. For this review the drive's firmware has been updated to version 1.07.
The look of NEC's drives really hasn't changed much over the last few years. While they've gotten new features and faster speeds, the basic look has remained the same. As you can see, the ND-4550A is no exception. Aside from the new "Super-Multi" logo, there really isn't much of a difference between it and NEC's previous 16x DVD±RW drives.
Below the tray you can see the ND-4550A's single LED. It lights up green when the drive is both reading and writing.
The rear of the ND-4550A is pretty straightforward. By looking at the picture below you can see the drive's IDE interface, power connector and audio output connectors.
Starting from the left of the IDE connection you'll see the jumper switch for master, slave and cable select. By default the drive's jumper comes set to master. Next to the jumper block is the analog audio connector. To the left of this is the digital audio output.

More Features:
By looking at the picture below, you can see that NEC's new DVD writer is identified as a "_NEC DVD_RW ND-4550A".
The Nero screenshot also shows that the ND-4550A has a maximum CD writing speed of 48x and a 2048KB buffer. This buffer is also backed up by some form of buffer underrun protection. According to Nero, the drive can also write CD-Text and overburn. Unfortunately, like some of the other NEC based DVD writers we've tested, it wasn't able to recognize our 99 minute CompUSA discs at all.
NEC's new drive seems to be able to do EFM encoding correctly. Using CloneCD version 4.2.0.2 with AWS disabled, Iwas able to reproduce older SafeDisc 2 protected titles like Max Payne along with some protected by SafeDisc 2.51 like Serious Sam: The Second Encounter.
Here is a screen shot from Nero's InfoTool. This program queries the drive to see what its reading and writing capabilities are. InfoTool had no problems detecting the ND-4550A's maximum reading and writing speeds, recording modes, buffer underrun protection and 2MB buffer.
InfoTool also shows that the ND-4550A is a RPC-2 DVD drive. This means that the drive's region is stored in the firmware. The drive's region can be changed five times and after that it cannot be changed anymore. A patched RPC-1 firmware can be downloaded here. Just keep in mind that it is not supported by NEC nor by CDRLabs. Use it at your own risk.
While InfoTool gives us a quick glance at the ND-4550A's features, DVDINFOpro provides a little more information on some of the drive's reading and writing capabilities. By looking at the screenshot above you can see that while NEC's new drive can read and write to DVD+R DL, DVD-R DL and DVD-RAM media, it does not support the Mt. Rainier format.
The ND-4550A doesn't let you set the book type of single layer DVD+R or DVD+RW media. However, using programs like CD Speed or Nero, you can set the book type for DVD+R DL discs to "DVD-ROM." This greatly reduces compatibility problems, especially with older DVD players.
Like NEC's previous DVD writers, the ND-4550A isn't short on features. Their new "Super-Multi" drive not only supports all major DVD formats, it sports some of the fastest DVD reading and writing speeds available. The ND-4550A is capable of 16x DVD±R, 8x DVD+RW, 6x DVD-RW, 8x DVD+R DL, 6x DVD-R DL writing speeds and a maximum DVD read speed of 16x. On top of that, it can read and write DVD-RAM media at 5x. NEC's new drive also includes features like a 2MB buffer and support for some sort of buffer underrun protection, but lacks bitsetting support for single layer DVD+R and DVD+RW media. Even then, the NEC ND-4550A scores a solid 8 out of 10 for its features.
