Once hooked up, the device can record single- and dual- layer discs at up to 22x (DVD) and 48x (CD). Like its cousin, it sports S.A.T. (Speed Adjustment Technology), which automatically burns discs at the most optimized speed, based on the strength of the CD. And when running at high-speeds, the unit’s Buffer Under Run Technology prevents Buffer Under Run errors from occurring—ensuring the process runs seamlessly without unwarranted blunders. Other notable aspects of the Samsung SH-S223F include an aerodynamic frame for reduced acoustic noise, double OPC technology for less writing errors, and automatic firmware updates.
