Physical Features:
The drive Plextor sent us for this review was manufactured in August of 2005 and had firmware version 1.01. It was also manufactured in China and had a TLA# of "0001". For this review we used firmware versions 1.01 and 1.02.
By looking at the front of the PX-740UF you can see that it is based on Plextor's internal 16x DVD±RW, the PX-740A. The two drives not only share the same bezel design, but many of the same logos. Below the tray you can see a few showing off its support for DVD+R DL, DVD+ReWritable, DVD-R/RW and Ultra Speed CD-RW media.
Measuring 6.58" x 2.09" x 9.98" (167.1mm x 53.0mm x 253.5mm) and weighing in at 3.52 lbs (1.6 Kgs), the PX-740UF is not the most compact or lightweight external drive we've tested. Nevertheless, the case is constructed of a durable black plastic that should stand up well to everyday use.

If you look closely, you can see that there is another LED on the top of the PX-740A. This LED lights up a bright blue when the drive is powered on. On each corner of the drive is a rubber strip. This strip not only keeps the PX-740A planted on your desk, it lets you position it either horizontally or vertically.
The rear of Plextor's new external writer also has its share of connectors. Starting from the left, you can see the PX-740A's FireWire ports, interface switch, USB 2.0 connector, on/off switch and power connector. I was a little surprised to see that the drive had a cooling fan, especially considering its power supply is located outside of the case in a small "power brick."

More Features:
By looking at the picture below, you can see that Plextor's external DVD writer is identified as a "PLEXTOR DVDR PX-740A."
The Nero screenshot also shows that the PX-740UF has a maximum CD writing speed of 48x and a 2048KB buffer. This buffer is also backed up by Sanyo's BURN-Proof buffer underrun protection. Technically, this isn't true as the drive uses a chipset from Philips, not Sanyo. According to Nero, the drive can also write CD-Text and overburn. When testing the drive's capacity, it had no problems overburning up to 99 minutes with our CompUSA media.
Like the BenQ DW1640, the PX-740UF can 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 of the newer ones 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 PX-740UF's maximum reading and writing speeds, recording modes, buffer underrun protection and 2MB buffer.
InfoTool also shows that the PX-740UF is an 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 Plextor nor by CDRLabs. Use it at your own risk.
While InfoTool gives us a quick glance at the PX-740UF'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 Plextor's new drive can read and write to both DVD+R DL and DVD-R DL media, it does not support the Mt. Rainier format.
The PX-740UF also supports a feature called "bitsetting." While the drive automatically sets the book type of DVD+R DL media to "DVD-ROM", you can manually do the same with single layer DVD+R and DVD+RW media using CD Speed. This feature comes in handy if you have an older DVD player that has problems playing recordable media.
