I've seen a couple year-end deals on 1 TB internal drives for under $300. 7200 rpm 32 mb....I'm looking to replace my original internal drive on my dual G5 2.5 and upgrade to Leopard and basically start over. Here's my question--I do a fair amount of video editing (Final Cut), is it better to just partition the TB drive for a scratch drive? Or get a smaller internal and then buy a 500gb external for the render files and such? I'm feeling the beginnings of a daunting task--upgrading RAM, a HD, and the OS....really hoping I don't screw up somewhere along the way.
