A flash drive usb is little and can fit in your pocket. It can Cary large files and important information and can be taken anywhere with you and put into any computer. A DVD while having many of the same qualities is bulky and large and needs a case of some sort to be carried in for protection.
A DVD cannot hold as much information as a usb drive.
