What are the advantages of using a USB Flash Drive instead of a CD-R or DVD-R?
USB ports are much more common than CD and especially DVD burners, so your USB flash drive will work with more computers than a CD-R or DVD-R. Also, the process of uploading files from your computer to a USB flash drive is much faster and simpler than burning a CD or DVD. Additionally, USB flash drives act like portable hard drives to which you can add and delete files as many times as you like. With CD-Rs and DVD-Rs, you can only add data once, and you can’t remove data once it’s burned onto the disc.
