Built Smaller And Faster From Input By Pros Like You.

The OWC Express 4M2 is designed with superior ease-of-use in mind. We worked with award-winning creatives and listened to the kudos they heaped onto the OWC ThunderBay mini, and we put all that shared knowledge to good use when we set out to build the next-gen Thunderbolt 3 multi-bay drive. The result is the 57% smaller and 2.5x faster OWC Express 4M2.

It’s smaller and easier to fit into your workflow, studio and on stage. It’s faster with four easy-access M.2 slots so you can swap, upgrade or expand your Express 4M2 to configure and reconfigure it to serve any project need.
