Hi guys, I have always used my Mini with the internal HD as the main one. It's 5400 rpm I guess, I can't recall because it's not the original one but a 160gb one since the old one fried (it says 1.5 gigabit in the 'about this Mac' section, this is 5400rpm speed right?) I also have an ATA external 120 7200rpm GB (bought when 120 GB was a LOT), but anyhow I just got a 1Tb 7200 SATA, just waiting for the Firewire case to arrive. My question is, which one of these drives would I get better speeds and performance using as my main one? The Firewire400 one or the internal 5400 drive? I guess there won't be any significant difference between the ATA and SATA one because they'll be both connected via FW400 so they won't reach their full speed (I'm right on this, am I not? Not sure lol). Thanks for any answers.
