Mac / PC / Thunderbolt 3 / DisplayPort 1.2 / RAID 5
The Speed You Need
All New Design for Power and Performance
ThunderBay 4, OWC's flagship 4-bay RAID powerhouse is bigger and faster than ever before. Now with the unbelievable performance of Thunderbolt 3 — up to 1527MB/s sustained performance1 — it's the ultimate workhorse external storage solution.
Not only faster, the new ThunderBay 4 Thunderbolt 3 is now natively compatible with both 2.5" and 3.5" drives, and with a redesigned chassis, it's even cooler and quieter too.
Edit, Experiment, Create, Design
Designed with performance in mind and engineered to harness the power of Thunderbolt 3, ThunderBay 4 is an incredibly flexible external solution with the throughput to support multi-stream compressed 4K video and other bandwidth-intensive operations.
ThunderBay 4 is highly configurable to perfectly match your performance needs. Choose between traditional hard drives or Solid State Drives. Use each drive independently, or in the RAID configuration of your choice for the optimal balance of performance and data-redundancy. Get the most out of your storage, take the brakes off your workflow, and do more with a ThunderBay 4.
Monitoring + Notifications
Easily setup drive monitoring and e-mail notifications to keep you informed about your ThunderBay's performance and drive health. Helping you to maintain mission critical workflows.
Certified and Tested
Each ThunderBay 4 undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly, ready for demanding use.
