A Blu-ray ROM (Read-Only Memory) typically has a capacity range of 25 GB for single-layer discs and 50 GB for dual-layer discs. There are also larger formats, such as BDXL, which can hold up to 100 GB on triple-layer discs and 128 GB on quadruple-layer discs. This higher capacity allows for more extensive data storage, making Blu-ray discs suitable for high-definition video and large software applications.
