nu DDW-163
Unlike the conventional DVD-writers, double-layered DVD-writers can burn up to 8.5 GB of data, and require a special 2.4X double-layered DVD R media for it. The nu DDW-163 is one such drive, which supports speeds of 16X write on DVD+/-R, 4X rewrite on DVD+/-RW, and 16X DVD-ROM read. Its CD-writing speeds are slower than the conventional CD-writers. It only supports up to 40X CD read/write, and 24X CDRW, while regular CD-writers support up to 52X. This can result in a difference of up to a minute in CD-writing. The double-layer DVD-R is roughly equal to 4 hrs DVD video quality and 16 hrs VHS video quality for TV recording. This drive also comes bundled with InterVideo for video playback/capture, and Sonic for creating music and data discs. We tested this drive on a P4 3.0 GHz machine with 256 MB RAM and 20 GB HDD. The media used were HCL 52X CD-R, 24X CDRW, 8X DVD+/-R and 2.4X DVD+RW and 2X DVD-RW. Unfortunately the 2.4X double-layer media is still not available in the market, so we couldn’t check that function.

DVD+/-R burning speeds are comparable to the BenQ DVD-writer that we’ve reviewed in this issue. We faced an issue while copying 4.3 GB data to the DVD-RW. It gave an error mid-way and only managed to copy up to 2.3 GB data. Even the BenQ drive gave the same error. The DVD burning/copying uses more CPU power than CD-writing in this drive. This can go up as high as 90%.

The Bottom Line: Overall an affordable drive with good DVD writing speeds.
