A Blu-ray disc can store how much data on a dual layer version?

A dual layer Blu-ray disc has the capacity to store 50 GB of data. This is achieved through its advanced technology that allows for two layers of data to be written on the disc, doubling the storage capability compared to a single layer Blu-ray disc, which holds 25 GB.

The capacity of 50 GB makes dual layer Blu-ray discs suitable for high-definition video and larger data backups, as they can hold more than twice the amount of information compared to standard DVDs. This feature is particularly beneficial for movies released in high definition, allowing for additional content such as bonus features or multiple language tracks without sacrificing quality.

Understanding the storage capacities of different disc types is essential for effective data management and choosing the appropriate media for various applications.
