The “Just Right” RAID for All Storage Needs
When two bays clearly aren’t enough storage for your needs and eight bays feels a bit ambitious for now, enter the ThunderBay 4. This “just right” Goldilocks of storage solutions offers the space, speed, and flexibility you can use for both current and future needs.

There’s a reason ThunderBay 4 is our most popular multi-bay RAID storage solution. You can use a variety of 3.5-inch or 2.5-inch drives for everyday digital file storage and backup all the way to running multi-stream compressed 4K video. With two Thunderbolt ports, it gives you the muscle to move all that content.

And ThunderBay 4 is highly configurable to perfectly match your storage needs. You can use each drive independently, or with OWC SoftRAID XT configure your setup with 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.

Cool. Fast. Empowering.
Each populated 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 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.

Gain a 4K Perspective
With a dedicated DisplayPort 1.2, ThunderBay 4 empowers you to add the fresh, crisp perspective of a 4K display to your workflow. Whether in your home office or on a mobile studio job, seeing your work in full detail is just one connection away. Use it to free up your laptop port so you can dock in and out quick.

The “Supply Chain” That Always Delivers
With two Thunderbolt ports, the ThunderBay 4 lets you daisy-chain up to five additional Thunderbolt devices and displays while keeping Thunderbolt ports on your laptop or desktop free for other uses.
