I currently have a 1TB and a 500GB disk as a concatenated disk on my computer. My iTunes library is stored on there and it sometimes takes a second or so to load up my library. As my library is fast approaching 1TB, what would be my best course of action? The Samsung Spinpoint F3 1TB is on ebuyer for £47 at the moment, which is a pretty nice price. Should I give up on Apple's software solution and look for a raid card that will give me RAID-0 for two 1TB disks? What would give the best performance? I can't afford a Drobo and don't want anything plugged in externally if possible.
