ok I am looking into getting an external hard drive for my 933 Ibook for use with cubase/live 3/peak and other stuff and I found 3 that seem to be good.

im looking at 160gb and I will be using firewire 400.

im just not sure if one of thoughs would be better than the other or if there is a better hard drive I should buy for music production.
