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 at up to 1527MB/s real-world throughput speed.

And ThunderBay 4 is highly configurable to perfectly match your storage needs. You can use each drive independently, or in the SoftRAID XT 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.

Cool. Fast. Empowering.

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.

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.

Thunderbolt Made Easy

We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer an adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.

Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.

OWC's ThunderBay 4 brings to the market capacities that have yet to be seen in such a compact medium, as well as the performance and data security that only RAID 5 can provide!

Easy and Complete Drive Management with SoftRAID XT

SoftRAID XT is the most powerful, intuitive RAID management software on the market for macOS and Windows. SoftRAID’s RAID creation and management technology has been finely tuned to perfection with over 20 years of development to provide rock solid protection of your data and optimize drive performance. It is packed with features like multiple RAID options, validation and verification of drives, and predictive disk failure with SoftRAID Monitor. SoftRAID provides a level of performance that you simply can’t get with hardware RAID.

Multiple RAID Levels

Create advanced RAID 0/1/4/5/1+0 (10)1 volumes for higher performance and/or redundancy.2

Disk Health

More accurate than SMART, SoftRAID protects your data by alerting you to issues before anything happens, providing peace of mind and giving you more time to address issues. Solutions that rely exclusively on SMART data can be seeing performance loss or corruption before flagging an issue.

Cross-Platform

Built-in MacDrive technology lets you read/write SoftRAID HFS+ RAID 0/1/5 arrays and use them interchangeably between Windows and macOS.

Flexible, Upgradeable

With SoftRAID you’re not locked to expensive hardware. SoftRAID is upgradable and portable.

Easy License Management

New license management enables quick activation or deactivation so your license can move between computers.

Compatible

Works with macOS 10.12 or later and Windows 10 and later.3

SoftRAID is ideal for anyone who needs to safely store and backup massive amounts of data, including video editors, audio producers, photographers and graphic designers.

  1. RAID 4/1+0 (10) is available for Mac only at this time.
  2. Improved data protection/redundancy requires RAID 1/4/5/1+0.
  3. SoftRAID serial numbers work on both Mac and Windows. SoftRAID is licensed per computer. In order to use SoftRAID on multiple computers, you will need a unique, valid license per computer. Additional licenses can be purchased anytime.

Workflow and Storage Solutions for Pros

Whether you’re finishing and mastering, creating proxies or working with state-of-the-art VFX and AR, you need dependable tech that keeps pace with your demands. OWC workflow and storage solutions cover every angle, delivering blazing speed, capacity for all five levels of RAID, and bonus features like the freedom to daisy-chain and hot-swap.
