I need to buy an external HD that has:

7200rpm
firewire built in

I found this: https://www.lacie.com/uk/products/product.htm?id=10553

But my daughter said to look and see if there were any alternatives, possibly with more storage for the same amount of money.

Do let me know.

The requirement these days for old Firewire means you're paying a premium over USB3 drives.

This is twice the size of lacie's 500GB 7200 RPM hard drive...

Firewire never caught on with the Windows crowd. And now Apple is dropping it from newer machines. With lesser demand, the supply drops off and prices rise.

Desktop or portable?

Does the Mac do USB3 or Thunderbolt? Either would be way faster than FW.

You can either purchase desktop or portable FW drive. An Alternative is to pick your own drive (2.5" for portable, 3.3" for desktop) and then pick your own enclosure. It is the enclosure, not the drive itself, that does FW. Later when the Mac gets replaced with one that does USB 3, you simply replace the enclosure...not the drive.

Easier still, get a drive with an enclosure that does both FW (for now) and USB 3 (for the future Mac). You can find them all day long at Newegg, Amazon....etc.

As we get closer to Black Friday....watch for deals.
