I suspect one of the drives on my 2009 Mac Mini Server is failing. If so, I can't wait on a possible Mac Mini Haswell model upgrade. My instinct is to buy a 2012 2.6Ghz i7 with single 256GB SSD. My intention would be to then buy a separate 2.5" 9.5mm HGST Travelstar 5K1500 (1.5TB) drive, to create a large capacity Fusion drive (I want to maintain my existing BootCamp partition on one of the drive's three separate platters). My understanding is that if I erase the 256GB SSD, install the additional 1.5GB drive, then Disk Utility will flag an error message before asking if I want to initiate a fusion drive installation. Is this correct? Or, would I need to enter Terminal to effect Fusion Drive?
