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.

Backed by OWC
You can rely on OWC's award-winning U.S.-based support for the ThunderBay 4 solution. Plus, ThunderBay 4 comes with an OWC Limited Warranty.

4 drive bays plus so much more.

Time-Tested Cooling
Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.

Multi-Drive
Daisy-chain up to six ThunderBay 4s for massive storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve exponential speed capabilities.

Vibration Dampened
ThunderBay 4's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.

DisplayPort 1.2 Support
Dual Thunderbolt 3 ports let you connect the display of your choice that your computer can support, including 4K displays.

OWC Thunderbolt Cable
ThunderBay 4 comes with a certified OWC Thunderbolt 3 cable.
