What is the Storage Capacity of Blu-Ray Discs?
Last Update date : Oct 12. 2020
A single-layer disc can hold 25GB.
A dual-layer disc can hold 50GB.
To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs.
