At the size of a pack of chewing gum, USB Flash Drive are far smaller than external hard
drives, and with no fragile moving parts that can break if dropped, they're
more easily transported. USB Flash Drives also do not require the
time-consuming configuration required to connect an external hard drive to your
computer.
USB ports are much more common than CD and DVD
burners, so USB Flash Drive will work with more computers than
CD-Rs or DVD-Rs. 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.
And it’s needless to remind that a standard
floppy disc, holding only 1.44 MB of data, doesn’t stand much of a chance in
front the very large storage space (up to 32GB) that a USB Flash Drive can
offer nowadays.
