Why would you want external hard drives? Just one more
thing to take up space on your already cramped up desk right?
Well...I can think of several reasons why you would want
external hard drives:
Portability - It gives you an opportunity of taking large amounts of
files or software with you, wherever you go, and you can plug them right into
another computer (external hard drives usually connects through the USB(2.0) or
FIREWIRE connector, or both). This is why these hard drives commonly are talked
about as portable hard drives too.
Backup - Burning backups to CDs or DVDs can be a tedious affair, if
you have a large amount of files, and they stack up quickly, even DVDs which
have more room. Much easier to have external hard drives that you can
connect, make the backup, then tuck away again;). Some of them even comes with a
button you can press and then it backs up all the files on your computer
Ease of use - External hard drives are much more easily installed
than regular internal ones. You just connect the USB(2.0) or FIREWIRE connectors
and the power cord and that's it. No head-scratching about which wire goes where
inside the computer;-).
External hard drives usually run at the same speed and
with the same technology as internal ones.
The only thing to consider is if you have a lot of other
equipment connected to the same USB(2.0) or FIREWIRE hub/card you might see a
decrease in speed as your hard drive is sharing the hub/card resource with the
External hard drives won't work well as your system/startup
drive, but other than that they are good hard drives
for any type of use.
