OWC
Express 1M2 USB4 Enclosure — Empty

Build an external NVMe drive around a compatible SSD and a faster host connection. Compare the full enclosure-plus-drive cost with a ready-made portable SSD. The added bandwidth matters only when the computer, cable and SSD can use it; a USB-C connector alone is not enough.
