48x CD-RW Combo Roundup Vol.1 - Page 1
With the market full of new and fast DVD recorders, some people may think that buying a combo drive (one able to record CD's and read DVD's) is out of fashion. There are several reasons in favor of this argument, but there are also also several others against it. Combo drives offer high CD-R/RW recording and reading speeds, a fast DVD reading speed and are significantly cheaper than DVD recorders. If DVD writing is not your first need, then a combo drive is what you need. We have in our labs two new combo drives, the Optorite DC4801 and the LiteOn LTC48161.
Most of us are already familiar with the Optorite series of optical products. The Taiwanese company offers a wide range of CD-RW and DVD recorders, as we have already tested in our previous articles. This time we take a look at the Optorite DC4801, a 48/24/48/16 combo drive.

Optorite DC4801 supports 48x CAV CD-R writing and reading. The maximum rewriting speed is 24x P-CAV, which means that we should probably expect very low rewriting times with respect to US-RW media. For the DVD format, Optorite supports 16x DVD-ROM reading, and 8x CAV for the DVD±R and DVD±RW media.
The provided buffer underun protection is called "BURN GUARANTEE". The EXACT-Rec feature monitors the writing process and ensures a high degree writing quality The supported AWSS (Advanced Weighting Suspension System) technology reduces vibration and noise, at high reading/ writing speeds.
