## Long description

The StarTech OWC Envoy Express portable NVMe SSD enclosure is a compact external housing for M.2 NVMe drives that supports up to 4 TB capacity. Finished in black aluminum, it connects via USB‑C with Thunderbolt 4 (40 Gbit/s) class performance for high-speed file transfers and on-the-go storage. The enclosure is bus powered through an integrated cable, offers plug-and-play compatibility with Thunderbolt/USB4 and USB‑C hosts, and is designed for reliable sustained transfers in professional and consumer workflows.
Advantages
The Envoy Express combines a small physical footprint and low weight with support for very high real-world transfer rates, making it suitable for fast backups, media capture, editing, and file delivery. Its anodized aluminum housing provides passive cooling and durable protection without a fan. Being bus powered via the integrated cable eliminates the need for an external power adapter and the removable slide mount enables convenient attachment behind a laptop screen for mobile use. The enclosure also supports built-in OS encryption features on macOS and Windows for secure data access.
Suitable for
On-location media capture and fast offload of high-resolution photo and video files
High-speed backups and archive tasks for laptops and desktops
Editing and playback of large media projects from an external NVMe drive

How to use

Connect the integrated USB‑C/Thunderbolt cable to a host device that supports USB‑C or Thunderbolt/USB4. The enclosure is bus powered and should be recognized by the operating system as an external NVMe storage device; format and partition the drive as needed for your workflow.

Usage recommendations
For maximum sustained performance, use modern NVMe SSDs rated for high sustained write/read speeds and connect to a Thunderbolt 4 or USB4 host.
