Hello everybody, I have an Apple iMac "Core i5" 2.8 27-Inch (Mid-2010) with 12GB RAM. I am currently booting it from a OWC On-The-Go Pro via FireWire 800 with a WD Scoprio Black 7200rpm running Snow Leopard. No BootCamp, no dual boots. Just OSX. My question is: Would it be considerably faster if I changed the WD with an SSD? And if yes, which model would you choose? I am not planning to open the iMac to install anything internally. I just want the flexibility of booting through an external drive and keep my data in the 1TB internal HDD (plus an extra external backup HDD where I backup everything weekly as well). So I am looking for the fastest possible performance via FireWire booting. I am sure an internal SSD would be much much faster but, as I said, I'm not going to open the iMac. The current size of my external (system) drive is 160GB but I am only using 50GB. Therefore, I'm not looking for a big capacity (and cost) SSD. What are your ideas?
