OWC Envoy Express Thunderbolt 3 enclosure
I must have missed this announcement but there seems to finally be a Thunderbolt 3 enclosure on the market after years of this connection being public. The OWC Envoy Express is a Thunderbolt 3 SSD enclosure that uses any 2280 M.2 NVMe SSD for super-fast speeds up and down. Wish I had known about this a few months ago (but was it out then?).
