I supposed that is because the JBOD box was handling the raid internally so short connection issues are not that problematic and can be recovered from automatically. But that wouldn't be the case if you connected everything together with a usb hub and usb to sata adapters and run a software raid on that.
I don't know usb c in thunderbolt has direct access to pcie lanes.
I've been running a 4-disk RAIDz1 on USB for 4 years now with zero failures on one machine and one failure on another where it turned out the USB controller in one WD Elements was overheating. Adhering a small heatsink on it resolved the problem and it's been stable under load for 2 years now. The USB devices have to be decent. AMD's host controllers are okay. VIA hubs are okay. ASMedia USB-to-SATA are okay. I'm using some enclosures with ASMedia and some off-the-shelf WD Elements that also use ASMedia. It's likely easier to get a reliable system if installing disks internally as the PSU and interconnects are much more regulated and any would work well, whereas with USB you have to be careful in selecting decent components.
