Ok I bought a Macbook Pro 15.4" 2.4 unibody which is the late 2008 model. I have had it for about 2 weeks now and I'm trying to slowly get the stuff I feel I need such as backpack, external, extra battery, elevator stand. But yesterday I found out that I can buy a ExpressCard/34 adaptor to run an external hdd. I was just wondering if that was faster and cheaper then just buying a external with firewire 800? Thanks for your advice in advanced.
