4.0TB Thunderbolt Bus-Powered Portable NVMe SSD 

The Super-Fast Xtremely Rugged Portable SSD
One Super Little SSD Beast
The mild-mannered exterior of the Envoy Pro SX hides its true nature. It’s super-fast. Super-versatile. Super-portable. Xtremely rugged to shrug off the most perilous work and play settings. When put to the test, this little beast of an SSD handles all data storage and backup challenges like a true superhero.
Super Versatile

Super versatile in use, it goes from being a bus-powered drive for daily storage and backup tasks to easily handling the super-fast demands of production-level audio, design, and photography workflows. And you can use it with today’s and tomorrow’s Thunderbolt and USB4 equipped Macs and PCs to enjoy Xtreme real-world performance speeds up to 2847MB/s1
The Best Made Better
Built along the award-winning lineage of the Envoy Pro EX, this tiny but mighty ½ pound portable drive is 1/3 smaller, features a removable Thunderbolt cable, and is IP67 rated and test certified to handle the nastiest environments. From handling obstacles in the field to deadlines at home, the Envoy Pro SX lets you unleash your productivity power without needing a cape or mask.
Form Meets Function
To ensure it works as good as it looks, the grooved fins on the Envoy Pro SX’s matte black aluminum chassis transform it into a highly effective heat sink. Even after a diabolically long file transfer, the stealthy silent Envoy Pro SX stays reliably fast.
