Like many, over the years I've acquired quite the mass of photos, documents, etc, that I have stored over various volumes and drives. I would like to bring these all together in a single volume for ease of access and backup. I'm looking for a direct attached storage system, where multiple drives can be swapped in and out in a RAID configuration (something like a Drobo). I've almost pulled the trigger several times before on one but have always been a bit put off by the price and less than great reviews. Any suggestions on a good enclosure that won't break the bank but doesn't skimp on quality either? Optimally 4-5 drive capacity would be perfect, and USB-C to connect to a 15"tMBP. Much appreciated.
