Advice for External Hard Drive Enclosure

I’m currently running a Dell desktop tower with external 1 TB hard drives plugged in via USB. I’m mainly using it as a Plex server running on Unraid OS. I haven’t had any problems so far, but I want to expand my storage significantly. I’m thinking of getting a TerraMaster D4-320 and plugging it in via USB-C. I have seen some good and bad with the external enclosure interacting with Unraid.

Is this a good idea? I can’t seem to find many people who’ve used that particular DAS with Unraid. Or should I take a different route?
