Miguel at ExtremeMhz has taken a look at Samsung's new Serial ATA equipped DVD writer, the SH-S183L. Along with 18x DVD±R and 12x DVD-RAM writing speeds, the SH-S183L supports HP's LightScribe technology. Here's a sample of what he had to say about it:
The biggest difference with this new model is its new SATA interface. However, don't expect a significantly higher level of performance with this drive over an IDE model. The biggest impact in performance was certainly the CPU usage. They are, by far, the lowest I've ever seen. This was expected though because an SATAI drive can indeed provide low CPU Usage over IDE. This was apparent is all read tests performed with this drive. Is it worth it? Honestly, the answer is no. For the most part, you'll get just as good performance with one of their older IDE models. Other than CPU usage, the other real benefit is that smaller cable.
Miguel also has some interesting insights about burning DVD's under windows Vista. If you'd like to read more, the entire review can be found here.
