There are external USB-3 cases that claim to support RAID on linux. Linux supports Thunderbolt 3, but I hadn't encountered external TB RAID arrays with Linux support before retiring in 2018. A search today found: T4-S12L.TB3 Thunderbolt 3 Four Tray-Less SAS (12Gb) /SATA III Support RAID with LCD Control For Mac, Windows And Linux https://www.datoptic.com/ec/portable-thunderbolt-3-four-sata-sas-ssd-raid-quiet-tower-lcd-control.html P16-R64L.TB3 - 64TB Thunderbolt 3 RAID: https://www.datoptic.com/ec/60tb-thunderbolt-3.html The specs say: "Must use Linux Kernel 4.13 with Ubuntu 18.04 & 17.10 <http://www.areca.us/support/s_linux/driver/ubuntu/18_04.zip>". I assume there are other vendors selling external TB3 or USB3 RAID boxes. I like external RAID arrays because you can plug them into a host configured for your needs and running the same OS as your other boxes. If you could afford it, you could get external RAID arrays with vendor supplied drives. The vendor gets statistics on drive performance for all their drives and I've heard of replacement drives arriving with a note telling you which drive it was meant to replace.. -- George N. White III
