What is the storage capacity of a standard single-layer Blu-ray Disc (BD)?

A standard single-layer Blu-ray Disc (BD) has a storage capacity of 25 GB. This is the design specification for single-layer discs and allows for high-definition video and audio storage, making it an ideal medium for movies and high-quality data.

The 25 GB capacity of a single-layer Blu-ray Disc is significant when compared to previous formats like DVD, which typically held about 4.7 GB for single-layer discs. This increased capacity enables the storage of more extensive content without compromising quality, which is crucial for the demands of modern high-definition media.

In contrast, the other options reflect the capacities of multi-layer Blu-ray Discs or different formats entirely. A dual-layer Blu-ray Disc can hold 50 GB, while options such as 100 GB and 128 GB are associated with even higher-capacity formats or specialized BDs. Understanding the differences in storage capacities among these formats is essential for anyone working with digital media and technology.
