Has someone already tried to make a Catalina bootable USB flash drive...

    USB 3.1 Gen 2 External SSD as Boot Drive

    Anyone here using a 10Gbps USB 3.1 Gen 2 SSD Enclosure with NVMe PCIe SSD as the Boot Drive? Is building a drive like this better than using a Samsung T5 you think? Will this be reliable for long term?
