Pint-Sized Powerhouse

Small in stature. Big on capability. The OWC Express 4M2 is ready to serve with four easy-to-access NVMe M.2 SSD slots customizable for any workflow with vibration damping feet that allow for vertical or horizontal orientation. Install up to 32TB of capacity and experience up to 2800MB/s of mind-bending performance via Thunderbolt 3. The Express 4M2 is an amazingly small digital workhorse with world-renowned OWC quality and award-winning support built in.

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.

Game-Changing NVMe SSD Performance

NVMe (Non-Volatile Memory Express) is a hyper-efficient communications interface protocol built from the ground up to properly take advantage of SSD technology and high-performance connection buses like PCIe. The result is exponentially faster and efficient SSD storage, and the OWC Express 4M2 has room for four NVMe SSDs.

DisplayPort

Display connection flexibility is yours with a convenient DisplayPort located right on the rear of the OWC Express 4M2. There's no need to worry about adapters or extra long cables. Just plug your display directly into the Express 4M2 and you're all set.

Thunderbolt Logo

Connect to Thunderbolt and Thunderbolt 2 Systems with Ease

The OWC Express 4M2 is fully backward compatible with Thunderbolt and Thunderbolt 2. Utilize Thunderbolt 3 performance to work at full speed, and step back to Thunderbolt or Thunderbolt 2 whenever connectivity compatibility is needed for your workflow. Add a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter along with the appropriate Thunderbolt cable, and you're all set.

Thunderbolt 2/Thunderbolt compatibility requires a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) adapter and a Thunderbolt 2 cable. This configuration provides data transfer at Thunderbolt 2 speeds (up to 20Gb/s) but does not support notebook charging.
