OWC Express 1M2 40G – 1TB Product Overview
The OWC Express 1M2 40G - 1TB combines a high-speed USB4 enclosure with a factory-installed 1TB NVMe M.2 SSD, providing a compact ready-to-use storage solution for demanding creative and production workflows.
Its USB4 40Gb/s architecture is designed to maximise performance on current USB4 and Thunderbolt-equipped systems while remaining usable with compatible lower-bandwidth USB-C connections.
1TB Ready-To-Run NVMe Storage
This exact OWCUS4EXP1MT01 configuration is supplied with 1TB of installed NVMe M.2 storage, avoiding the need to source and install a separate SSD.
Up To 3836MB/s USB4 Performance
OWC specifies real-world Express 1M2 performance of up to 3836MB/s when connected to a suitable USB4 40Gb/s or Thunderbolt 4 PC host. Actual performance varies with host platform, workload and connection type.
Wide Host Compatibility
The Express 1M2 is compatible with USB4, Thunderbolt 5, Thunderbolt 4, Thunderbolt 3 and supported USB-C devices. It automatically operates at the maximum speed available from the connected host interface.
Passive Aluminium Thermal Design
The solid aluminium enclosure doubles as a large passive heatsink, dissipating heat from the installed NVMe SSD without a fan and helping maintain consistent performance during sustained transfers.
Portable Bus-Powered Operation
The Express 1M2 receives both power and data through its USB-C connection, so no separate power adapter is required. A 0.3m USB-C 40Gb/s cable is included.
Professional Workflow Applications
The combination of high throughput, silent operation and portable construction makes the Express 1M2 suitable for editing high-resolution video, fast media offloads, photo libraries, scratch storage, backup and other data-intensive workflows.
