I'm looking for a thunderbolt 3/USB-C drive enclosure of some sort to use with a new 2018 mac mini. I have 4x 4tb 3.5" hard drives and i'd like to put them in a RAID 5. I'll primarily use this drive for photo work with lightroom. Photos are also backed up online and I periodically back them up to another drive that I keep elsewhere. I was looking at OWC Mercury Elite Pro Quad Raid edition or Akitio Thunder 3 Quad X(but looks like I have to purchase software to raid this?) Or a Drobo 5C. Any thoughts on these or additional recommendations? I'd like to keep the cost for the enclosure under $350.
