Store More, See More, Do More

With the ability to daisy-chain you can add up to five additional ThunderBay 4 mini solutions to create massive storage capacities. Merge them with SoftRAID for even more flexibility, capacity, and capability. Or if speed is what you’re after, connect multiple ThunderBay 4 mini solutions to multiple Thunderbolt ports on your Mac or PC to achieve exponential speed capabilities.

Beyond storage, the sky is the limit for what you can connect. Attach a 5K Thunderbolt display or two 4K displays. Place a USB 3.1 device at the end of the chain. With an extra Thunderbolt port, you have the flexibility to add to your daisy-chain and master any task at hand.

Thunderbolt Made Easy

We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer an adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.

Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.

OWC ClingOn

Work with Ultimate Confidence

Active workspaces expose gear to unexpected bumps and shoves. OWC ClingOn custom cable stabilizers (sold separately) screw into the OWC ThunderBay’s housing to reduce – if not completely eliminate – cable strain on Thunderbolt and USB-C connections so you can work with ultimate confidence even in the highest foot traffic environments.

Professional Grade

Professional Grade = Ready to Work

We understand having confidence in gear reliability is paramount to creative professionals. That’s why every ThunderBay undergoes OWC's multi-hour "burn-in" performance certification prior to shipping. This ensures your ThunderBay arrives operating properly and immediately ready for demanding use.

OWC Thunderbolt (USB-C) Cable

OWC Thunderbolt Cable Included

OWC ThunderBay solutions come with a certified 0.7M OWC Thunderbolt (USB-C) Cable. But if your workflow demands a different length to make the connection, OWC Thunderbolt (USB-C) Cables are the perfect choice.
