Edit, Experiment, Create, Design

Designed with performance in mind and engineered to harness the power of Thunderbolt 2, 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 undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay arrives operating properly and ready for demanding use.

Time-Tested Cooling

Built on OWC's time-tested enclosure cooling technology, ThunderBay 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's 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 ThunderBays for massive storage capabilities and increased performance, or connect multiple ThunderBays to multiple Thunderbolt 2 ports to achieve exponential speed capabilities.

DisplayPort 1.2 Support

Dual Thunderbolt 2 ports let you connect the display of your choice that your computer can support, including 4K displays.

OWC Thunderbolt Cable Included

ThunderBay 4 comes with a certified OWC Thunderbolt cable, with other lengths from 0.5 meter to 30 meters available separately.

SoftRAID: Conventional Wisdom Turned on its Head

It's often thought that hardware RAID is better than software RAID, but we’ve proven that not to be true. We've combined the performance and capacity of the ThunderBay 4 with our robust SoftRAID engine. Experience breathtaking performance, multi-enclosure capability, advanced drive monitoring, e-notifications and downloadable updates. Once you do, you'll see how hardware RAID doesn't even come close.

The Better and Simpler Way to RAID

We created SoftRAID to make it easier to maintain mission-critical workflows to save you time and money. With SoftRAID you no longer need to be locked into expensive hardware RAID technology that’s not upgradeable or expandable. SoftRAID future-proofs your data and storage with software updates that provide cutting edge capabilities and robust stability.

SoftRAID takes advantage of your computer's processor versus the slow processors found in most hardware RAID enclosures. The result is a fast and flexible RAID array with no discernible impact to your favorite apps. SoftRAID drive certification tells you whether or not a drive is up to the task before creating a RAID array. Advanced monitoring tools work behind the scenes to keep your RAID running in tip-top shape.

SoftRAID protects your data by alerting you to issues before anything happens, ensuring you're protected when you’re on a critical deadline. SoftRAID rebuilds your RAID in a fraction of the time it would take a hardware RAID to complete the same task, sparing you from significant downtime when you're ready to upgrade or replace a drive.
