I'm looking to purchase a 4-bay (or more) drive enclosure which I can configure as RAID5 or similar, preferably rack mounted but I'm really struggling to find anything that's not a NAS. I don't really need NAS features, and would prefer just to have something that's either USB-C or Thunderbolt 2 or 3. It will be used for backing up video files and I was planning on populating it with Seagate IronWolf 8TB drives. Any recommendations?
