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 drive with the throughput to support multi-stream compressed 4K video and other bandwidth-intensive operations. Highly configurable to perfectly match your performance needs. 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 undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly and 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 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.

Vibration Dampened

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

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.

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 Included

ThunderBay 4 comes with a certified OWC Thunderbolt 3 cable, with other lengths from 0.5 meter to 2.0 meters available separately.
