What is one advantage of optical storage?

Optical storage is characterized by its ability to retain data without needing a continuous power supply, which is referred to as being non-volatile. This means that the data stored on optical media, such as CDs, DVDs, and Blu-ray discs, is preserved even when the device is powered off. Non-volatile storage is particularly advantageous for users because it ensures the longevity and integrity of the data, making it an ideal choice for archiving and backup purposes.

While optical storage also provides other benefits, such as relatively low production costs and decent storage capacities, it is the non-volatile nature that truly highlights its key advantage, especially compared to volatile memory options that require constant power to maintain data.
