4 TB USB4 portable SSD

The OWC Express 1M2 80G delivers 4 TB of external storage in a bus-powered enclosure that connects through a single USB4 Type-C cable. It is aimed at creators and mobile professionals who need internal-drive speed while working away from a desk. The drive ships ready to run or can be purchased as a DIY kit for user-supplied M.2 modules.

USB4 interface limits

Peak real-world transfer reaches 6000 MB/s with a maximum read rate of 6362 MB/s, but sustained throughput depends on the host controller and cable quality. The drive requires Mac OS 14.x or higher or Windows 11 or higher to operate. Operating temperature range is 41 °F to 95 °F; storage range extends from -4 °F to 140 °F.

DIY upgrade and installation

A finned aluminium chassis acts as a heatsink, allowing tool-free access to the M.2 2280 or 2242 slot for future NVMe upgrades. The included 0.3 m (12") USB4 cable is short, so desk placement must be planned. Cross-platform Mac and PC use requires separate MacDrive software.

Questions sur cet article

Should I choose the DIY kit or the ready-to-run 4 TB version?

The DIY option lets you install your own M.2 2280 or 2242 NVMe SSD, while the ready-to-run unit ships with the 4 TB drive already fitted. Both use the same aluminium heatsink enclosure and included 12" USB4 cable.

What does the 6362 MB/s headline figure mean for everyday transfers?

It is the maximum read transfer rate under ideal conditions; real-world peak speeds exceed 6000 MB/s, so large video files and project folders move at near-internal-drive pace when the host supports USB4.

Which USB standard does the drive use and what speed does it cap at?

The drive uses USB4 via the supplied Type-C cable, delivering up to 6362 MB/s maximum read transfer rate on compatible Macs, PCs, iPad Pros, Chromebooks and Surface devices.
