As for “FILE,” it allows for easy, quick, and painless backup of data in just 3 easy steps. This is not the only enhancement sported by the writer; it also includes SMART-BURN for zero under-buffer-run errors, SMART-X for enhanced data extraction, and an ABS system that ensures there is no noise during recording. 

Additional Information

Despite this unit's wide array of features, it does lack LightScribe disc-labeling technology. If this is a necessity, then please review either the DX-20A3H or DX-20A4H.
