High-Capacity Storage Built for Creative Workflows
From large 4K and 6K video projects to RAW photo catalogues, multi-track audio sessions and long-term archives, ThunderBay 4 brings large capacity and fast direct-attached storage into a compact desktop enclosure. Choose the drives and RAID configuration that suits your workflow, then scale your setup as the project library grows.
Four Universal SATA Bays - Your Drives, Your Workflow
The ThunderBay 4 enclosure accepts four 2.5-inch or 3.5-inch SATA drives without forcing a single storage approach. Configure it with high-capacity HDDs for an archive, SATA SSDs for faster production work, or a combination designed around your own needs.

- Ideal for DIY drive configurations, selected RAID solutions and centralised backup.
- Locking front panel helps protect installed drive trays.
- Premium aluminium enclosure with vibration-absorbing feet.
- Flow-through venting and a low-turbulence fan support reliable operation.
Thunderbolt 3 Connectivity and Daisy-Chain Flexibility
Dual Thunderbolt 3 ports make the ThunderBay 4 an adaptable part of a professional desk or studio. Connect it to a compatible Mac or Windows workstation, add compatible storage devices through the second Thunderbolt port, and build a cleaner direct-attached storage workflow.

SoftRAID - Choose Speed, Capacity or Protection
With OWC SoftRAID support, ThunderBay 4 can be configured around the requirements of each project. RAID 0 delivers high throughput, RAID 5 balances capacity and one-drive fault tolerance, while other supported configurations provide different combinations of performance, redundancy and independent-disk flexibility.

Made for Video, Photo, Audio and Studio Archives
ThunderBay 4 is made for the everyday storage pressure of modern content production. Use it to work directly from a large project library, consolidate smaller external drives, create a robust on-desk archive, or add flexible local storage capacity to a production workspace.
