Both the usb flash drive and the dvd are data storage devices, but they both have numerous differences. both can contain insane amounts of data and add to our storage making it even easier to store your photos, videos, and many more types of files. however, the ways both devices operate are very different. the dvd requires a port and a laser to scan the extremely small bumps on dvd thousands of times per minute. this process may take longer than simply plugging your usb drive into a usb port. because the usb has no moving parts, it is faster than to use the dvd drive and it is silent. the newly invented usb flash drive contains 32gb while the older dvd contains about 4.7gb. regardless of the differences in technology and age, both devices are great data storages.
