There are a number of options... I will list them in the order I think
1) Install an additional IDE Harddrive
2) Add external Firewire drive
3) Add external USB drive
You will also find that $500 is heaps, and will get you almost
anything you like.
The informations I have found suggests that your computer does not
have any Firewire ports, so the second option may not be available to
The details --
1) An additional drive is going to give you the best $/GB ratio - as
an external drive is just an IDE drive in an expensive case really.
The downside is, it involves either a technician or your own work -
which could invalidate a warranty (although on a three year old
computer that may not be a problem).
2) Firewire is preferable as it is faster. That's the main reason - if
those two ports are indeed Firewire then it's the best option for an
3) USB is another external option, and because of the way USB works,
you can always extend the number of USB ports you have. However it is
much slower than either of the other two, and may not be suitable for
high-bandwidth media (such as very high-quality video). USB 1.1 will
only operate at 12MBit/s (1.5MByte/s) - which is fast enough for MP3s
and the like, but not fast enough for DV (which is around 3.6MByte/s).
What to do for each one --
1) Buy an IDE harddrive - I personally like Seagate Barracuda drives.
They are affordable, fast and reliable. An 80GB Barracuda can be had
from BestBuy.com for $140. Once you have the drive, installing it is
actually quite straight forward - here are some links:
If that's not to your tastes, the the cost of hiring a tech for this
(usually) simple task is probably less than you'd pay for the external
2 & 3) There are many external drives available - it's simply a matter
of finding the right one. First you need to determine if you have a
firewire port - this image
from the Iomega Zip drive manual, shows the normal symbols for a
firewire port, and this one
shows a firewire port (on the right, note the arrow shape).
If you have a Firewire port, look for a firewire drive. Otherwise you
will need to use a USB1.1 drive, also, if you have no USB ports free
on your computer, you will need a USB hub. You will find that many (if
not most) external drives are now dual-mode Firewire/USB2.0 - they
should be find, so long as they are USB1.1 compatible.
Here are some products (these are from BestBuy, but feel free to shop
