My new 2012 2.6 I& mac mini is sitting in my receiving room, waiting for me stuff it full of Samsung 840 Pro SSD and 16GB Corsair goodness. I'm curious as to what people are doing with the included 5400 RPM Hitachi Drive. Based on various forums I'd seen people: 1. Leave it in there as a second drive for backup and storage 2. Slap it into USB 3.0 enclosure as backup and storage 3. Fuse it to SSD to make fusion drive 4. Add second SSD and forgo it all together. I'm just wondering what you decided to do and why? Is there a performance perk to putting it in a USB 3.0 enclosure vs leaving it in there? Thanks.
