I'm buying an external HD today and have decided its gonna be a LaCie. I need to know whats the best for my MINI and why? 1. LaCie Ethernet Disk mini 2. LaCie d2 Extreme with triple Interface 3. LaCie Big Disk Extreme 4. LaCie d2 Serial ATA Ideally I would like the Serial ATA to eventually set up as a RAID 0 array but can I do that on a mini?
