http://www.digitalfaq.com/media/dvdmedia.htm second link tells you. It's either 2nd or 3rd class which isn't bad. "Decent discs, though not perfect, about 80-95% success rate. These discs are not suggested for archival data or video masters. These are best suited for data that can be replaced easily, such as secondary backups or data/video distribution. In bulk, these tend to be less expensive than 1ST CLASS media."
