Portable SSD for creators and mobile users

The OWC Express 1M2 80G is a 2TB NVMe drive built for creators in the field and mobile performance enthusiasts. It connects via USB4 and delivers real-world peak speeds over 6000MB/s. The drive works with Mac OS 14 or higher, Windows 11 or higher, iPad Pros, Chromebooks, and Surface devices. Its silver aluminium finned enclosure dissipates heat silently to maintain consistent performance.

Included cable and software options

A 0.3M USB4 cable is included for bus-powered operation. The drive accepts user-installed M.2 2280 or 2242 NVMe modules for future upgrades. Cross-platform Mac and PC use requires OWC MacDrive software, which is sold separately. No other bundled software or accessories are provided.

Tool-free M.2 installation

The enclosure opens without tools so you can insert a 2280 or 2242 NVMe drive. Ensure the module is seated fully and the thermal pad contacts the aluminium fins. Operating temperature range is 41°F to 95°F; exceeding this can cause throttling. The drive measures 2.8 by 5.2 by 0.9 inches and weighs 9.9oz.

Questions about this item

Can the internal M.2 2280 NVMe module be swapped for a larger 2242 or 2280 drive later?

Yes, the enclosure is designed for DIY upgrades and accepts both 2280 and 2242 NVMe M.2 SSDs for future capacity increases.

At what point does the aluminium finned heatsink stop preventing thermal throttling during long transfers?

The patent-pending heat-dissipating design keeps the drive cool for consistent top speed across the 41°F to 95°F operating range without active cooling.

How much power does the bus-powered USB4 connection draw when the drive runs at 6000 MB/s all day?

The drive is fully bus-powered through the included 0.3 m USB4 cable and requires no external adapter for sustained 6000 MB/s real-world performance.
