Looking at getting an external harddrive. I have seen a few and they all seem around 500gb which is more then enough for what i need, now 500gb would be a waste of time to me if i can't (for example) store a program/game on it, due to buying a harddrive would be so that i can keep anything school related on my macmini itself so that when i take it to school its there, and then all other memory hogging apps/files on the harddrive for use at home. I have firewire ports on my macmini so im guessing getting an external harddrive that uses firewire cables to connect is the best way about it. So basically heres what im asking. Will an firewire external harddrive be quick enough or even capable of running apps off, of? If not, are they even quick enough to pull music off, of (for example, putting all my music on the external harddrive and having iTunes on the macmini harddrive, will the songs lag as they change)? What sort of price am i looking at for a decent sort of external harddrive and are there any good ones with about 150gb memory due to 500gb being way more then i need? Any recommendations on hardrives/were to buy them? Will it cause any-problems if i am unplugging it to take my macmini to school if i have apps on it (obviously not ones that i am going to use). ------------------------- Projectors.. anybody got any recommendations?
