FWIW, the T7 is not an NVME enclosure per se, but rather a "portable hard drive." Its issues are well documented in forums.[0][1][2] I've known a couple friends in real life who've owned it as well, and they ran into the same issues I did.

I'm now using an OWC Envoy Express Thunderbolt 3 enclosure with a 4 TB WD Black SN850X and have no issues whatsoever. Very happy with this solution!
