Which optical media has the greatest storage capacity?

DVD-R
Single-layer, single sided Blu-ray disc
DVD+RW
CD-ROM

The correct answer is: Single-layer, single sided Blu-ray disc

The single-layer, single-sided Blu-ray disc has the greatest storage capacity among the listed optical media. It can typically store around 25 GB of data, which is significantly more than the other options. To understand the context of this capacity, look at the other types of optical media for comparison. A standard DVD-R, for instance, has a capacity of about 4.7 GB for single-layer discs and can increase to 8.5 GB for dual-layer discs, which is still less than a single-layer Blu-ray. DVD+RW has similar capacities to DVD-R, typically allowing for the same 4.7 GB in single-layer format. Meanwhile, a CD-ROM has the least capacity, generally allowing for up to 700 MB of data. This distinction in capacity makes the single-layer, single-sided Blu-ray disc the clear choice when considering storage limits across the various formats.
