OWC ENVOY EXPRESS is not reliable for all drives... I had two and they destroyed two SSDs for me. There is a lot of discussions online about this. I had to return the devices which was too bad considering that I really liked the design.

The online discussions talk about the type of SSD that has chips on both sides are failing in the Envoy and only the expensive OWC drives are working consistently. I ended up going with the Sabrent 4TB Sabrent Rocket XTRM was on sale at Amazon for $699 and includes an external enclosure with a removable rubber protecter. I use TB for my Logic and other sound libraries which is great speed and a 3" SSD for Windows and other project stuff
