After the DW1640 released several months ago, BenQ expands its optical storage range with yet another release, an upgrade to the DW1625, the DW1655. A quick look at the drive's specifications, will reveal that the main upgrades from the previous release are 16X for DVD -R up from 8X, 8X up from 4X for +RW, 6X from 4X for -RW, 8X from 2.4X for DVD +R DL, while now also supporting DVD -R DL at 4X.
Apart from this, there are also writing quality improvements which we'll be having a look at. All tests have been updated since the preview of the drive presented recently so we will be going through our usual array of tests, including writing quality and error correction in the course of this review but we'll begin with a quick look at the drive's main features...
Here is a list of the drive's main features as found on the official BenQ optical storage web site.
BenQ has launched its DW1655 DVD ReWriter with LightScribe Direct Disc Labeling Technology, to dress them up. LightScribe Technology will enable you to easily create customized, silkscreen-quality labels directly on CDs and DVDs using their own PCs through a combination of LightScribe-compatible media, recordable optical drives and special software. Burn, Flip, Burn
The BenQ DW1655 is Solid Burn embedded, meaning that it automatically learns to optimize writing quality, therefore ensuring maximum compatibility.
Write Right Technologies
BenQ's exclusive Write Right Technology utilizes two powerful features: Tilt Control and WOPC II (Walking Optimal Power Control II). By using these features the DW1655 is able to maintain perfect control over both the laser beam angel and the power rate being projected onto the disc, ensuring every bit of your data is written at the best possibly quality.

- The Drive
We received the bulk version, accompanied with a DVD Re-Writer Software Disc (Ver.2.4 which is also included in the bundled version), containing several applications such as the Nero Suite, QSuite v2.1, Lightscribe v220.127.116.11, Quick start guide and Acrobat Reader. For more information about the bundled version of the drive, you can look it up on the official BenQ website, here.

Removing the cover renders the drive's warranty void. You can have a closer look at the drive itself, as well as inspect the chipset used in the DW1655, by clicking on the image below, which will produce a larger, more detailed view of the inside of the drive.
The chipset used is once again made by Philips (as in the BenQ DW1640 drive), but this time is the PNX7862EL, seen in the picture below.
We installed the drive under WinXP as a master and it was identified as "BENQ DVD LS DW1655". From Nero's advanced options dialogue, we can disable the buffer under-run protection as well as the DVD high compatibility mode. The drive came with the latest firmware installed.
As it has become customary to do with the latest release review drives, we will be comparing the drive's performance with that of two other latest drives, the Plextor PX 755A and the LiteOn 1635S.
So let's move on to the rest of this review of the BenQ 1655, starting with the DVD reading capabilities.
