Both the Samsung SW-252B and Lite-On LTR-52246S have support for buffer underrun protection and the standard barrage of CD-RW features. However, both products are aimed at a different segment of the marketplace. The Lite-On drive has superior reading speeds, but at the expense of twice the CPU utilization percentage of the Samsung SW-252B and does so while creating a small racket. Whereas the SW-252B and its 8MB cache was able to prevent the once-common buffer underrun error under extensive use of available system resources... all while emitting far less drive noise. The Samsung SW-252B is late to market, but the drive brings peace and quiet to those that seek quieter sytems without an impact on overall drive performance.
