History-Making DIY Pocket-Sized Storage Solution

While small in stature, the OWC Envoy Express is big news. For the first time ever in the history of Thunderbolt™, you can buy a bus-powered Thunderbolt™ certified enclosure and install your own drive in it. Finally…a DIY kit that lets you break free of pre-configured choice limits so you can build a pocket-sized storage solution to meet your specific needs. And rebuild it anytime those needs change. Equally revolutionary is the included slide mount. This surface-safe removable drive holder allows you to slide the Envoy Express onto the back of your laptop’s screen for out-of-the-way mobile use convenience. More options. More usability. More functionality…only from OWC.

The Power of Build Your Own Options

Build your Envoy Express with a brand-new drive for a fast boot drive. Retask an existing drive replaced during an upgrade for added storage and backup capacity. Or, use Envoy Express to regain access to files on a drive removed from an inoperable machine. Whatever the reason you want to build your own bus-powered Thunderbolt enclosure, Envoy Express gives you the power to make it happen.

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!

Uses Today’s and Tomorrow’s Drives

Designed to support any NVMe M.2 2280 SSD, the Envoy Express gives you the freedom of flexibility to use any drive today – including the OWC Aura Ultra III with capacities up to 8TB – as well as being ready for tomorrow's 16TB and future capacities without limit.

OWC recommends OWC Aura Ultra III NVMe M.2 SSDs starting at $69.99.

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. Besides being the industry’s first Thunderbolt™ 3 bus powered (no power adapter required) enclosure, the Envoy Express is the first to include a laptop mounting system.

Removable adhesive gel and a lightweight yet durable plastic holder secure the Envoy Express onto the back of your Thunderbolt™ 3-equipped Mac or PC laptop screen. Easy to add and easy to remove with no marking or marring.

  1. Drive not included. Performance results will vary depending on user installed drive. 1553MB/s performance based on testing a 2.0TB OWC Aura Ultra III 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).
  2. “Thunderbolt Compatible” devices are those that are not true Thunderbolt solutions, but utilize the same USB-C connection. While computers with Thunderbolt (USB-C) ports support all USB-C devices, only true Thunderbolt devices offer the higher performance capabilities, certified reliability, and stability that Thunderbolt is designed to deliver.
