Samsung SE-W162C/EUBN Lite-On's EZ-DUB DVD burner simplifies copying and backup of files via two buttons on the top of the drive. The disc copy takes place in three steps: insert the original disk, press the DUB button and replace the disk with a blank to record. You can also back up data by dragging files to the EZ-DUB folder and pressing the FILE button. The EZ-DUB provides high performance, with up to 16x writing speed for DVD+/-R and up to 4x for DVD+R. It also supports CD-R writing up to 48x and CD-RW up to 24x. It has a high speed plug-and-play USB 2.0 connection for easy and fast burning. Lite-On SMART-BURN technology and 2 MB buffer reduce recording errors, while SMART-X technology monitors and adjusts reading speed for optimal performance. In addition, the vibration absorption system reduces vibration and noise when using the unit.
