While Blu-ray might have won the HD war, the platform really hasn't gained too much for use as a storage medium but is gaining some ground with high definition movies. With the PX-B310U you get an external DVD burner with a bonus, the added ability to watch Blu-ray discs. The included suite of PlexUtilities and Cyberlink BD Suite gives you everything you need to fully utilize DVD burning and Blu-ray watching right out of the box.
