I am in the process of setting up a Mac Mini as my main desktop to replace a Hackintosh where all the storage is internal (A hodgepodge of a 7200 2TB data drive and an old 5400 1TB backup/TM drive, with the main OS being on a 128G SSD). I'm looking to repurpose as much as possible of my existing drives (Don't like waste). The plan is to fit the Mini with a 256G SSD (internal) for OS and main drive. But I would like to re-use my HDD in some sort of external enclosure (USB 3) to complement the Mini. I also have 2 7200 2TB WD greens in a NAS which I find to be rather slow (compared to USB 3 or internal speeds) and am not married to keeping the NAS as it doesn't get much use in its intended purpose (over the Network). My thinking is to use 2 or 3 of the 7200rpm 2TB drives in a RAID of some sort, on an external USB 3 enclosure that will be permanently attached to the Mini, and using the 2 5400 drives in the NAS (strictly for TM backups). I've looked at various USB 3 enclosures and am not entirely sure which way to go. I don't really need the enclosures to provide the hardware RAID as I am perfectly happy using the OS X RAID capabilities (nothing mission critical here). What concerns me is, reading the various reviews on the different enclosures has yielded a ton of doubts and questions. I see a lot of complaints about some enclosures not playing well with Macs: Anything from random disconnecting of the USB 3 drives to ones that never power down or go to sleep under OS X). I've also seen complaints about loud fan noise, unreliable hardware and so on. What's the consensus or what suggestions do you all have? Anyone else around here using somewhat similar setups? What do you use? What have you found? PS: I am not interested in a TB enclosure as they are too costly and do not provide much added benefit to me. Plus I intend to use the TB port from the Mini for my display (27" Dell monitor, via DP).
