CDs store up to 700 MB, while DVDs hold 4.7–8.5 GB. Choose DVDs for larger files or videos, and CDs for music, documents, or smaller data storage needs.

CDs hold about 700 MB, while DVDs store 4.7–8.5 GB. Use a CD for audio or small files, and choose a DVD for movies, backups, or larger data.

Storage capacity is the biggest difference between CDs and DVDs. CDs typically hold 700 MB, while DVDs store 4.7–8.5 GB, making DVDs better for larger files and videos.

The biggest difference is storage capacity. A standard CD holds about 700 MB, while a single-layer DVD holds 4.7 GB, so DVDs are much better for videos, large backups, and software. I still use CDs for music sometimes, but for almost anything else, I'd choose a DVD because it stores much more data and is more practical.
