I just purchased a refurbished 27" iMac (September 2013. Unfortunately, I didn't have enough money to buy one with a SSD or Fusion drive, and I am stuck with a 1TB internal drive at 7200rpm. Originally, I was just going to purchase an external SSD and boot from it, but I have decided that I would rather use a hybrid/fusion drive. Will a hybrid drive even work properly in an enclosure? If not, any recommendations on a cheaper external SSD? I was hoping to get the following hybrid drive with a decent USB 3.0 or TB enclosure.
