Ok, so I want a RAID array that is compatible with Apple Mac OSX (and windows PC, preferrably, so I could later reformat the drives to NTFS if I so desired). I will be using it for video editing. I am planning to setup 4x1.5tb HDDs in a RAID-10 array (so I'll have 3gb storage with 100% redundancy). Does this sound right so far?
My question is, do I need to buy an external setup such as this 3ware (for $850):
(would this be Mac Compatible and have everything I need? Why does the other one cost $500-$650 more?). I am also wondering if RAID-10 is the best way to go for speed & redundancy, and why some of these enclosures have 5 hdd spots? Why 5?
