OWC Express 1M2 80G 1 TB portable SSD (OWCUS4V2EXP1MT01)

Portable NVMe SSD with USB4 interface

The OWC Express 1M2 80G is a 1 TB external solid-state drive built around an M.2 2280 NVMe module. It connects via USB4 Type-C and draws power directly from the host through the included 12 inch cable. The silver aluminium enclosure acts as a heatsink to sustain high transfer rates without throttling. It is aimed at mobile creators and enthusiasts who need internal-drive speed in a rugged, bus-powered package.

Suits USB4 hosts; not for older ports

This drive delivers its peak real-world speed above 6000 MB/s only when attached to a USB4 controller on Mac OS 14 or higher, Windows 11 or higher, iPad Pro, Chromebook or Surface devices. Buyers whose systems provide only USB 3.2, USB 3.1 or USB 3.0 connectivity will see substantially lower throughput and should look at a drive matched to those interfaces. The DIY option also requires the user to supply a compatible 2280 or 2242 NVMe module.

Maximum read transfer rate 6362 MB/s

The supplier rates the maximum sequential read transfer rate at 6362 MB/s, a figure that decides whether the drive meets a project’s bandwidth needs. Real-world peaks exceed 6000 MB/s on capable hosts, matching internal NVMe performance for demanding creative workloads. If your workflow requires sustained writes or random IO at a specific level not quoted here, verify those numbers before purchase.
