Envoy Express 
4.0TB Thunderbolt 3 Bus-Powered NVMe M.2 SSD

Rocket-Fast Drive with Galactic Sized Capacity
Portable Storage Rocket
While small in stature, the OWC Envoy Express offers a huge diversity of uses. Its 1553MB/s of real-world speed lets you perform on-location downloads of large media content like 8K video, high-res photo, and audio files in a blink. Imagine transferring 5GB of GoPro footage in just three seconds! Weighing a mere 3.3 ounces and shorter than a ballpoint pen, the Envoy Express puts personal and work files in the palm of your hand. For the ultimate in out-of-the-way mobile use convenience, you can place the Envoy Express on the back of your laptop’s screen with a removable slide mount. More options. More usability. More functionality…only from OWC.
Backup, Play, and Edit. Faster.
Whether you want to backup your growing photo and music libraries, share files, play your favorite games and movies anywhere, or even want to capture and edit up to 8K video, the Envoy Express can do it all. And it’s built to support super-fast sustained data transfer rates up to 1553MB/s…often faster than your machine’s internal drive performance!
Built for Highest Reliability
Engineered with fail-safes, the Envoy Express is optimized for the best and longest working life, especially in write-intensive workflows. From running double checks on data and correcting errors to ensuring the uniform use of its flash media, this high-performance portable NVMe SSD is calibrated for endurance as a factory pre-set.
Small Footprint. BIG Convenience
The Envoy Express is compact and lightweight. Since the Envoy Express is bus powered via its integrated 10-inch Thunderbolt cable, there’s no power adapter needed. Nothing to forget, nothing to lose. Just pure Plug and Play convenience at your fingertips with Thunderbolt and USB4 Macs, PCs, and iPads.
Gets Onboard with Macs and PCs
Today's office is often a tiny bistro table, your lap in a remote location, or a cramped airplane seat. There's no power outlet and not enough room for an external drive. The Envoy Express is the first to include a notebook mounting system. 
Removeable adhesive gel and a lightweight yet durable plastic holder secures the Envoy Express onto the back of your Thunderbolt™ 3-equipped Mac or PC notebook screen. Easy to add and easy to remove with no marking or marring.
Need to share the Envoy Express? It can work cross-platform with Macs and PCs using OWC's MacDrive software(sold separately). Peace between the platforms.
Store from Minutes to Millions
All the features and “technospeak” of an external drive don’t mean a thing if you don’t know how much of a particular file type it can hold. For every 1TB of your OWC drive capacity, you can store up to any of the following: 
  • 250,000 photos
  • 250,000 standard quality songs
  • 38,000 high quality songs
  • 200 high-definition movies
  • 41.6 hours of GoPro 4K footage
  • 4.3 million MS Office documents
  • 24+ PS4/Xbox games
Secure It All
If you have sensitive client project files or personal information that requires access permission, the Envoy Express is fully compatible with macOS and Windows built-in encryption so you can add peace of mind password security to your data.
Difference Making Truth
Big theoretical performance numbers are certainly eye-catchers…but they rarely reflect real-world performance. That’s why we take the extra time to run OWC storage solutions through intensive performance testing. Truthfully listing the Envoy Express up to 1553MB/s real-world test results defines our commitment to the “OWC Difference” which ensures you’ll be completely satisfied the Envoy Express will handle your most demanding needs.
OWC, Trusted by Pros & Enthusiasts Around the World
We build our hardware to the highest standards of reliability and performance. Because 100% reliability is always the goal, we rigorously quality test and back the Envoy Express with award-winning customer support.
1553MB/s performance based on testing a 2.0TB OWC Aura Pro P12 equipped Envoy Express connected to an iMac Pro Late 2017 (iMacPro1,1) with 32GB RAM and 3.2GHz processor running AJA System Test (4K-Full resolution, 16GB file size, 10bit RGB codec, single file test).
