I am running a 2007 20" iMac that is getting annoyingly slow (as you may know if you've seen some of my other posts). I'm debating switching now and holding out for whatever haswell has to offer. In the meantime, I'm exploring options and thinking about possibly picking up this USB 3.0 Firewire 800 enclosure and a 256 GB Crucial M4 SSD to use as my boot drive. Would this setup using Firewire 800 boost performance over my internal 320 GB 7200 stock hard drive? I have no experience using FW 800, so it's a bit foreign to me as to the benefits of the connection.
