Hi, I am going to be purchasing a Mac Mini at the weekend and a FW800 500gb portable HDD. Will this portable HDD be fine for storing all my iTunes library? (Movies, Music etc...) iTunes content will be downloaded direct to the library on the FW800 HDD and then the Mac Mini will stream content to my Apple TV wirelessly..(802.11n network) Can anyone see any major flaws in this setup (data speed, lag etc)? or advise me any better? Thanks in advance!
