Which Optical Disk Type Has The Highest Storage Capacity?

The type of optical disk with the highest storage capacity is the Blu-ray disc. A single-layer Blu-ray disc can hold up to 25 GB of data, and a dual-layer Blu-ray disc can hold up to 50 GB of data. That’s enough space for about 5 hours of high-definition video or 13 hours of standard definition video.
