Outstanding design milled from solid aluminum. Lightening fast. I'm so happy with it I bought another one.

The OWC Express 1M2 USB4 Portable NVMe M.2 External SSD Enclosure in Silver is the ultimate tool for creative professionals seeking unparalleled performance and reliability. This versatile enclosure allows you to build the portable drive of your dreams, whether you're repurposing an existing drive, starting fresh with a new one, or opting for the advanced technology of an OWC Aura SSD-powered solution. With the Express 1M2, you can enhance your workflow with real-world speeds of up to 3151MB/s, ensuring ultra-fast data transfer and seamless editing capabilities, even for 4K video.

Designed for ultra-compatibility, the Express 1M2 works effortlessly with USB4, Thunderbolt, and USB-C computers and devices, making it a future-proof choice for both current and upcoming technology. Its aircraft-grade aluminum construction provides rugged protection while silently dissipating heat, ensuring your SSD remains cool and performs consistently at top speeds.

The Express 1M2 offers powerful choices for customization. You can build your own drive using NVMe M.2 2230, 2242, or 2280 SSDs, or select a pre-configured OWC Aura SSD solution. Its portable, bus-powered, and palm-sized design makes it convenient to use anywhere, and it comes complete with a USB-C (40Gb/s) cable and screwdriver for easy assembly.

As the fastest single portable SSD offered by OWC, the Express 1M2 is engineered to maximize the performance capabilities of USB4-equipped Macs and PCs from 2020 and newer. It also maintains flexible compatibility with millions of older Thunderbolt and USB-C devices, ensuring you can edit demanding content like 8K RAW video and ultra-high-resolution photos without a hitch.

Unlike budget alternatives that fail to meet Intel specifications, the Express 1M2's USB4 connectivity guarantees maximum speed and reliability. This enclosure is built to handle demanding needs, with a solid aluminum heat sink design that prevents thermal throttling, ensuring consistent maximum performance. Its secure, screw-together construction protects your drive, and with OWC MacDrive software (available separately), it can work cross-platform with both Macs and PCs.

Ideal for photo and video professionals, DITs, and performance enthusiasts, the Express 1M2 provides an affordable yet robust solution for backing up and editing high-demand content. Ready to go right out of the box, it comes formatted in the native APFS macOS and iPadOS file system, eliminating the need for reformatting. With OWC, you can trust in the ease-of-use and reliability that have made their products a favorite worldwide. Plug in your drive, and you're ready to create without limits.
