ThunderBay 4 RAID
2.0TB 4-Drive SSD Storage Solution with Dual Thunderbolt 3 Ports

Mac / PC / Thunderbolt 3 / DisplayPort 1.2 / RAID 4
The Speed You Need
All New Design for Power and Performance
ThunderBay 4, OWC's flagship 4-bay RAID powerhouse is bigger and faster than ever before. Now with the unbelievable performance of Thunderbolt 3 — up to 1527MB/s sustained performance1 — it's the ultimate workhorse external storage solution.

Not only faster, the new ThunderBay 4 Thunderbolt 3 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, ThunderBay 4 is an incredibly flexible external solution with the throughput to support multi-stream compressed 4K video and other bandwidth-intensive operations.

ThunderBay 4 is highly configurable to perfectly 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.
Monitoring + Notifications
Easily setup drive monitoring and e-mail notifications to keep you informed about your ThunderBay's performance and drive health. Helping you to maintain mission critical workflows.
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, ready for demanding use.
Backed by OWC
You can rely on OWC's award-winning U.S.-based support for the ThunderBay 4 solution. Plus, ThunderBay 4 comes with an OWC Limited Warranty.

4 drive bays plus so much more.
Time-tested Cooling 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.
Multi-Drive 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.
Vibration Dampened Vibration Dampened
ThunderBay 4's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.
DisplayPort 1.2 DisplayPort 1.2 Support
Dual Thunderbolt 3 ports let you connect the display of your choice that your computer can support, including 4K displays.
Thunderbolt Cable OWC Thunderbolt Cable
ThunderBay 4 comes with a certified OWC Thunderbolt 3 cable.

Standard Mechanism

  • Release Candidate (RC) firmware set

    There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

    Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

    It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

1. Setting up a RAID volume for Windows requires the use of the Disk Management application, as SoftRAID is Mac only at this time.
2. Thunderbolt/Thunderbolt 2 compatibility requires a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) adapter and a Thunderbolt 2 cable. Compatibility will be at Thunderbolt/Thunderbolt 2 speeds.
3. For units purchased prior to 12/24/18, please see the OWC ThunderBay 4 Support Page for instructions on how to update your ThunderBay's firmware.

Rating: 5/5 Great drives May 6, 2019 Outgrew my Western Digital hard drives and needed a big, safe, fast drive. Found OWC ThunderBay drives and not looking back. This is my second one. Equipment is super solid and support staff is fantastic. No need to look anywhere else.

Rating: 4/5 Excellent choice July 25, 2018 This is my second ThunderBay 4 so that must say something. The other (with ThunderBolt 2) has been in constant use 24/7 for several years without out a single error. Which is why I bought another one with Thunderbolt 3. With four 4TB 7200 RPM HGST disks it is blazingly fast and provides enough storage for my image and video editing.

I had one slight problem with a RAID 0 volume mixed in with two RAID 5 volumes. I like to create a RAID 0 scratch volume to provide scratch and cache space for all of my photo/video tools. For some reason this particular system combination (hardware, software, disks)does not like this combination. My other ThunderBay 4 is fine with this config. So I whacked the RAID 0 volume and made it RAID 5 and all is well. Support is supposedly looking into this.

Rating: 5/5 Works well with my Mac server May 29, 2018 Purchased it to use my Mac mini server as a replacement for an older NAS. It worked right out of the box. Setting up the partitions was easy. So far, it's been great.

Rating: 4/5 A screamer, but somewhat noisy April 23, 2018 This unit is fantastically fast. Make no mistake about that. It transfers files faster than you can imagine, compared to other interfaces. It's reliable, and the software included does a great job of keeping everything in order. But if you are adding this to a new Mac, be aware that the new High Sierra OS on an iMac Pro prevents the included software from installing properly. You have to visit the Software manufacturer's website ( SoftRAID) for instructions on how to properly install it. If you don't do this problems will arise and you will likely find your data damaged and your disks having to be rebuilt which takes forever. done properly, though, this machine is stable, extremely fast, and generally goes un-noticed while doing its thing. Except for the noise. With a normal PC with spinning hard drives, this box would likely not be heard. But with an iMac or iMac Pro, it sounds loud and somewhat annoying. I almost returned it because of that, but its just too good at it's job to replace.

Rating: 5/5 Thunderbay 4 with RAID 5 March 7, 2018 This is the second one of these that i've purchased - the first being about 3 years ago. I have been very happy with the performance and reliability so this was a no brainer for me when i needed another one.

I now have 2 on my desk, one for personal use and one for photo/video professional use.

Rating: 4/5 Thunderbolt 3 Raid enclosure that meets expectations February 22, 2018 Just received the product and placed four 7200rpm HDD that I had available into it. After installation, the SoftRAID XT software (that I had to find and download - not as easy as the included pamphlet led me to believe) told me that one of my HDDs would fail sooner than later and to replace it. I replaced the problematic drive and the machine has been running flawless ever since (about a month now). I would give the hardware 5 stars but the SoftRAID XT software was 3 stars due to the challenge finding the right version and installing the serial number from the bottom of the hardware.

I would recommend this item to a friend! This review is from OWC ThunderBay 4 RAID 5 4-Bay External Storage Enclosure with Dual Thunderbolt 3 Ports. Customer Videos:
