The new Sony DRX-S70U-W sports a slim design and supports up to 8X DVD±R recording speeds, delivering a full 4.7 GB disc of video, data, music or images on standard 8X DVD+R media.
In addition, the new Sony drive can record on 8.5GB DVD+R Double/Dual layer and 4.7GB DVD-RW discs at 6X speeds, DVD+RW at 8X, DVD-RAM at 5X and CD-R/RW at 24X.
The DRX-U70-W comes bundled with the Nero DVD/CD mastering software suite, and offers quick and easy connectivity with a high speed USB (USB 2.0) digital interface for simple setup and maximum flexibility.Sony already has a DRX-U70 on the market. I assume the key is to look for the W in the product ID.
