I just began to ask about this in my other thread, sorry for that. What I need is fast help because I need to decide in the next few hours.... First I wanted to upgrade my new mac mini with a Momentus XT but now I'm thinking about getting a "real" ssd + a FW800 drive for storage to have the huge speed boost of the ssd drive. Does anybody have this combination in his mini? What I want to know: How is the performance like of the external drive connected to FW800? Is it comparable to a standard internal hard drive? Which way would you go? Thanks for your fast hints!
