What is the strength of a DVD?

The strength of a DVD lies in its ability to store large amounts of data—typically around 4.7 GB for a single-layer and up to 8.5 GB for a dual-layer disc—while providing relatively high-quality video and audio playback. DVDs are also durable and resistant to environmental factors like dust and scratches when handled properly. Additionally, they can be easily replicated and distributed, making them a popular medium for movies, software, and games. However, they have been largely supplanted by digital formats in recent years.
