This versatile DVD drive from Lite-On reads and writes DVD+/-R single and double layer discs, so you can record double the data on a single disc. Double-layer DVD media records up to 8.5GB of information on one disc, which equals approximately 16 hours of VHS-quality video or 4 hours of DVD-quality video.
The Lite-On SHW-1635SX writes DVD+/-R discs at speeds up to 16x and DVD+R double layer discs up to 8x. This drive also writes CD-Rs and read CD-ROMs at speeds up to 48x. It features a high-speed, plug-and-play USB 2.0 connection that makes disc burning projects fast and easy.
Lite-Ons SMART-BURN technology and a 2 MB buffer combine to minimize recording errors. SMART-X technology monitors and adjusts read speeds for smooth performance. And the Vibration Absorber System reduces vibration and noise.
