OWC Envoy Pro EX USB-C SSD Has ‘Jaw-Droppingly Good Performance’

If you have been a Rocket Yard reader for any length of time, you know that this blog has never existed to merely prop up OWC or We highly value our role in bringing you a wide variety of expert tips, commentary, reviews, and the latest tech news. However, we do take great pride in who we are and what we do as a company, and as the reviews for the new OWC Envoy Pro EX USB-C keep pouring in, we thought we’d engage in a little unapologetic sharing!

What the Experts are Saying

“…the 2019 OWC Envoy Pro EX USB-C SSD races past every other USB SSD that MPG has yet tested.”
“…insanely fast speed for a device of this type.”
“…almost no deviation in performance for the entire 2TB capacity written continuously. This is a jaw-droppingly good performance suitable for just about any task.”

On June 25th, OWC announced the release of the Envoy Pro EX USB-C SSD, claiming it was the fastest USB-C SSD ever built and brought to market. Well-respected photographer, computer expert, and software engineer Lloyd Chambers of Mac Performance Guide put that claim to the test. Here is what he found…

  • I wish we had a reasonably priced Envoy level external SSD made for thunderbolt 3 speeds. When will OWC or someone else offer this? What would be the speed advantage of a Thunderbolt 3 connected SSD maximized for Thunderbolt 3 throughput in a small size like Envoy?

  • Please, include QuickBench benchmarks for all your SSD web pages, as you used to do in the past. That is very useful to choose the best one.
