General Features
Updated Design for Power and Performance
ThunderBay 4, OWC's flagship 4-bay RAID powerhouse is bigger and faster than before. Now with the performance of Thunderbolt 3 up to 1550 MB/s sustained performance, it's a workhorse external storage solution. Not only faster, the ThunderBay 4 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, the ThunderBay 4 is an incredibly flexible external solution with the throughput to support multi-stream compressed 4K video and other bandwidth-intensive operations. The ThunderBay 4 is highly configurable to 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.
 
Certified and Tested
Each ThunderBay 4 solution 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.
 
Time-Tested Cooling
Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.
 
Multi-Drive
Daisy-chain up to six ThunderBay 4 enclosures for massive storage capabilities and increased performance, or connect multiple ThunderBay 4 enclosures to multiple Thunderbolt 3 ports to achieve exponential speed capabilities.
 
Vibration Dampened
The 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 3 Cable
The ThunderBay 4 comes with a certified OWC Thunderbolt 3 cable.
