External DVD drives and burners
offer great convenience for those without built in burners or
for those who have multiple machines or a need for data portability.
The drive is connected to your computer through a cable (usually
USB cable) which provides the data connection and the power for
the unit itself. With an external DVD drive, you can store large
amounts of data in a very small space for a very low cost. These
drives are fairly inexpensive and there is really little overall
difference in drives for the typical user. Here are some of the
options that should be considered before buying an external DVD
Comparison to other devices: The external
dvd drive, and particularly the external dvd burner is superior
to other mass media storage options. Here is a brief comparison
of popular choices:
to Internal Burners: The external offers portability
from machine to machine without having to undergo a physical installation.
Most burners simply require plugging in the USB cable, and some
my have a power cord as well.
to USB Flash Drives: While flash drives offer superior
speed, the fact that a flash drive offers limited data storage
is a definite drawback. If you plan on leaving your files on a
flash drive forever, that is one thing, but most people use them
for temporary storage and moving files. A blank DVD is a fraction
of the cost of a flash drive, and can easily be stored or given
to others, where a flash drive cannot.
Compared to CD Drives and Burners:
The amount of storage on a DVD is far greater than that of a CD.
The CD burner is now essentially obsolete for data storage. Most
DVD burners can burn CD's as well.
Overview For most users there is little difference in DVD
drives. What you really need is a good reliable drive at a decent
price. Several online vendors or big box stores offer a good selection
of top external dvd drive models.
If you don't have a lot of experience in buying
computer hardware, several sites offer hardware reviews which
provide both editorial and customer reviews. Online websites also
offer deeply discounted drives due to their high volume compared
to retail stores. You can save a significant amount of money and
get a piece of equipment that will last for many years. It is
good to comparison shop as well, because many sites depend on
volume sales, meaning they will sell the item a lot cheaper.
