The original 1TB hard drive that came with my 2012 Mac mini i7 crashed. I am considering replacing crashed drive with a 500 GB Samsung EVO SSD. I have a spare 1TB HD and was thinking to create a fusion drive with the two drives, is this a good idea or should keep the two drives separate ? Also, the $160 500 GB EVO has great specs but I can buy a 1TB OCZ Trion SSD for about $70 more ( which kills the budget). Considering to lower performance of the Trion , is it Better to buy the larger but slower Trion or the smaller but faster Samsung or will I even notice the speed difference? Thanks!
