This fan favorite USB4 enclosure is defined by its aggressive, finned design that seems intent on being serious business – and keeping things cool, too.
Performance That Doesn't Mess Around
With its USB4 interface, the Express 1M2 is designed for maximum speed. Paired with a high-speed drive, you're looking at real-world speeds in excess of 3,000 MB/s.
- When utilized in Macs with Apple Silicon (M1 through M4), you can anticipate up to around 3,189 MB/s.
- Connect it into a supported PC via a supported USB4 or Thunderbolt 4 PC, and those speeds may jump higher still, topping out at 3,836 MB/s.
It arrives pre-bootstrapped with a necessary included 40 Gb/s USB-C cable that is connected into the lone port on the device. OWC even goes so far as to include a screwdriver to assemble.
Appears and Construction
The chassis is "aircraft grade" aluminum and feels luxurious. Its raw, heatsink-like appearance definitely makes it the showpiece on a desk, whether you're a Mac enthusiast enjoying the aesthetic or a PC builder enjoying the hint of industrial look.
