Which optical media offers the highest data storage capacity?

• A. DVD-R
• B. CD-ROM
• C. Single-layer, single-sided Blu-ray disc
• D. Dual-layer, double-sided DVD

Answer: (C)

The choice of the single-layer, single-sided Blu-ray disc as the correct answer is based on its superior data storage capacity compared to the other options listed. A single-layer, single-sided Blu-ray disc can hold approximately 25 GB of data. This is significantly more than a DVD-R, which typically holds about 4.7 GB for single-layer discs and 8.5 GB for dual-layer discs. In comparison, a CD-ROM has an even lower capacity, generally around 700 MB. The dual-layer, double-sided DVD does increase total capacity, potentially reaching up to 17 GB, but still falls short of what a single-layer Blu-ray can store. Thus, the single-layer, single-sided Blu-ray disc offers the highest data storage capacity among the options provided, making it the most suitable choice for applications requiring larger amounts of data storage.
