DIY portable NVMe enclosure

The OWC Express 1M2 80G is an aluminum enclosure that accepts a single M.2 2280 or 2242 NVMe drive. It connects via USB4 and is bus-powered, so creators and mobile professionals can add high-speed external storage without an external power supply. The drive itself is not included.

Aluminum heatsink with USB4 cable

A finned aluminum body acts as a silent heatsink to prevent thermal throttling during sustained transfers. The enclosure measures 5.2 by 2.8 by 0.9 inches and weighs 9.9 oz. A .3 m (12") USB4 cable is permanently attached for host connection.

Screwdriver and cross-platform software option

The package includes a small screwdriver and an assembly manual for tool-free drive installation. OWC MacDrive software, sold separately, enables read-write access to Mac-formatted volumes on Windows 11 or higher and macOS 14.x or higher systems.

Questions about this item

What real-world speed does the USB4 80G interface deliver with this enclosure?

The USB4 80G interface supports peak real-world speeds over 6000MB/s when a compatible NVMe M.2 SSD is installed.

Which M.2 form factors fit inside the 2.8 by 5.2 by .9 inch aluminum enclosure?

The enclosure accepts both 2280 and 2242 NVMe M.2 SSDs, secured with the included screwdriver.

How is the drive installed and which step is most often missed?

Open the finned aluminum case, insert the M.2 SSD at an angle, press down and fasten the screw, then reassemble the enclosure; the step most often missed is fully tightening the retention screw before closing the lid.
