OWC Express 1M2 USB4 (80Gb/s) Bus-Powered Portable NVMe SSD

The OWC Express 1M2 USB4 (80Gb/s) Bus-Powered Portable NVMe SSD is a compact external storage enclosure that accepts a single M.2 NVMe drive and connects to hosts via USB4 for up to 80Gb/s theoretical bandwidth. Designed for users who need high-performance portable storage, the enclosure is bus-powered so no external power adapter is required. It delivers low latency and high throughput suitable for transferring large files, backing up systems, and supporting video editing or other data-intensive tasks when paired with a compatible USB4-capable host.

Advantages

The enclosure supports USB4 connectivity, enabling higher sustained transfer rates and reduced latency compared with older USB versions. Bus-powered operation simplifies portability by eliminating the need for an additional power supply. The compact form factor and M.2 NVMe compatibility allow users to install a wide range of NVMe drives to tailor capacity and performance. The design focuses on efficient thermal management and straightforward cable-based connectivity for plug-and-play use on supported systems.

Suitable for

• High-speed file transfer between computers
• On-location video editing and playback from external NVMe storage
• System and data backups requiring fast write speeds
• Portable expansion of storage for content creators and professionals

Key specifications

• Interface: USB4 host connection for up to 80 Gb/s theoretical bandwidth
• Drive form factor supported: M.2 NVMe (single module)
• Power: Bus-powered operation via USB4 connection; no external power adapter required
• Compatibility: Works with hosts that support USB4; backward compatibility with earlier USB standards subject to host limitations
• Enclosure type: Portable, compact design optimized for thermal performance

How to use

Install a compatible M.2 NVMe SSD into the enclosure following the included mounting instructions, secure the module and close the enclosure, then connect the device to a USB4-capable host using a compatible USB4 cable. The host operating system should recognize the NVMe drive as an external storage device; format the drive as needed for the intended operating system and workflow. For optimal performance, connect to a system with native USB4 support and ensure the NVMe module is rated for high-speed operation.

Usage recommendations

Use a certified USB4 cable and connect to a host that explicitly supports USB4 to achieve maximum throughput. Monitor drive temperatures during sustained heavy workloads and ensure adequate ventilation. For critical backups and editing projects, maintain secondary copies of important data and verify file integrity after large transfers.
