OWC‘s Express 1M2 80G Unleashes Thunderbolt 5 Performance
Table of Contents
The cutting-edge Thunderbolt 5 technology, recently popularized by Apple’s latest MacBook Pro, is now accessible through a new hardware offering. Other World Computing (OWC) has unveiled the Express 1M2 80G, a portable SSD enclosure designed to maximize the speed potential of Thunderbolt 5 while maintaining compatibility with older standards.
Elevated Performance for Creative Professionals
OWC’s Express 1M2 80G enclosure is engineered for professionals and content creators demanding high-speed, on-the-go storage. This bus-powered drive leverages the capabilities of Thunderbolt 5, yet remains fully functional with Thunderbolt 4 and USB4-equipped Macs and PCs, offering a versatile solution for a wide range of systems.
Currently, thunderbolt 5 functionality is exclusive to Apple’s newest M4 Pro and M4 Max MacBook Pro models, the M4 Pro Mac mini, and the mac Studio.Though, the Express 1M2 80G ensures compatibility with a broader spectrum of existing Mac hardware.
OWC advertises real-world transfer speeds exceeding 6,000 MB/s, rivaling the performance of internal SSDs found in recent MacBook Pro models.While sequential transfer tests may still favor internal drives, the Express 1M2 80G demonstrates comparable speeds and can even surpass them in random read and write operations.
Did You Know? Thunderbolt combines PCI Express and displayport into a single serial signal, enabling data transfer and video output through one port [[3]]?
This makes it an ideal solution for offloading large video projects, running applications directly from external storage, or efficiently managing extensive photo libraries.

The enclosure’s all-aluminum construction serves as a heat sink, ensuring sustained performance without the need for active cooling.
Beyond macOS, OWC confirms compatibility with Windows PCs, iPad Pro devices, Chromebooks, and Microsoft Surface products.
Pricing and Availability
The enclosure is available for purchase at $219, allowing users to install their own NVMe M.2 SSDs up to 8TB. Pre-configured versions are also available, starting at $349 for a 1TB drive and scaling up to $1,299 for an 8TB configuration.
The OWC Express 1M2 80G is currently available for purchase directly from OWC and through Amazon.
Pro Tip: Consider the read/write speeds of your chosen NVMe SSD when configuring the enclosure to maximize performance.
