Summary

Samsung's premier CD-RW works smoothly and quietly. At the normal 52X read/write speed, it was slightly quieter than the 352 combo drive, but at the forced 24X speed, it was slightly noisier. No complaints about noise in general, which was modest. There were no anomalies during operation; performance seemed much as claimed, and no unwanted coasters were created. Like the combo drive, this Samsung is smooth and reasonably quiet.

Much thanks to Samsung Canada for the review sample and their kind support.
