Which optical media has a maximum capacity of 50GB on dual layer discs?

The correct answer is Blu-Ray. Blu-Ray discs are specifically designed for high-density data storage, making them an excellent choice for high-definition video and large data files. A single-layer Blu-Ray disc can hold up to 25GB of data, while a dual-layer Blu-Ray disc can hold up to 50GB. This significant storage capacity is a key feature that distinguishes Blu-Ray from other optical media formats.

In contrast, DVDs, including the DVD-5 format, typically have a maximum capacity of 4.7GB for single-layer discs and 8.5GB for dual-layer discs. HD DVDs also have a similar capacity range, allowing up to 30GB on a dual-layer disc but falling short of Blu-Ray's maximum. CD-ROMs, on the other hand, offer much less storage, typically holding around 700MB of data. The advanced technology and capacity of Blu-Ray discs make them ideal for media that demands high-quality content delivery, such as movies and large software applications.
