How much can blu ray store?

A standard single-layer Blu-ray disc can store up to 25 GB of data, while a dual-layer disc can hold up to 50 GB. There are also BDXL discs, which can store up to 100 GB on a triple-layer disc and 128 GB on a quadruple-layer disc. This high storage capacity makes Blu-ray an ideal format for high-definition video and large data files.
