The larger storage capacity of a Blu-ray disc is a clear advantage over standard DVDs, allowing higher quality of video and audio to be stored. A standard DVD can hold up to 4.7 GB of data.
Detailed explanation-2: -But makers of storage systems and recording media are developing ways to read and write using more efficient blue lasers. Because these lasers operate at shorter optical wavelengths, they can write more data in the same space and write and read data faster than devices that use red lasers.
Detailed explanation-3: -Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red, 650 nm laser. Originally Blu-ray Disc could store 25 GB on each layer, and now they can hold 100 GB.
