Portable Storage Rocket
While small in stature, the OWC Envoy Express offers a huge diversity of uses. Its 1585MB/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 1585MB/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.
Removable 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 MacDrive software (available 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 1585MB/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.
Ready to go. Right out of the box.
OWC products are loved around the world for It Just Works™ ease-of-use and reliability. To provide the highest performance, reliability, and ready-to-run convenience available, your solution comes formatted in the native APFS macOS and iPadOS file system. With OWC, you don’t have to worry about reformatting hassles or confusion like other solutions — just plug your drive into your Mac or iPad and you’re good to go.
