I will soon be replacing my 2008 24" iMac with a fully loaded 27"... I'm holding out until the Fall to see if there's an update. While i wait... I'm trying to decide what type of hard drive configuration to get. For reasons I don't even know or can explain... I am wary of the Fusion Drive. It just seems like moving all those files around will double the trouble for things to go wrong. Yes, I'm probably showing my ignorance on how the system works. And I'm completely open to being educated on the subject. But... here is my question: I own a fair amount of movies and videos... most are stored in iTunes. I also have lots of pictures and home videos in my Photos.... so I need a fair amount of storage. I also stream movies and TV shows from various sources like Amazon Prime, Netflix and Flixter. So... what is the best hard drive for streaming? Does the Hard Drive impact the streaming speed... or does it make no difference? How would a Fusion Drive work when streaming video? Thanks for the help!
