Sony today added a designer USB-based DVD rewriter tailored for notebooks. The DRX-S70U-W is only just larger than the drive itself and records single-layerDVDs at 8X; it can also burn rewritable discs at the same speed and dual-layer 8.5GB discs at 6X. The drive is powered by the USB bus and is intended first for netbooks and ultraportables where optical storage isn't built-in.
