Conquer High Bandwidth Demands
With Thunderbolt 3 offering real-world transfer rates up to 2586MB/s and the ability to RAID together eight SSDs or HDDs, ThunderBay 8’s rugged, field-tested aluminum design has the under-the-hood horsepower needed to conquer high-bandwidth requirements. You can even configure multiple ThunderBay 8 solutions connected via multiple Thunderbolt 3 ports on your Mac or PC to achieve exponential speed increases. Whatever your set up, when you’re racing against a deadline, ThunderBay 8 puts you in the winner’s circle.

Monstrous Capacity
Need even more capacity? Daisy-chain up to six of these capacity behemoths together for up to a staggering 768TB. Now you can capture vast amounts of footage from multiple cameras or store vast libraries of production work with a unified and reliable storage solution.

Includes SoftRAID: Easy and Complete Drive Management
Now you can quickly access and robustly protect your data with SoftRAID Lite XT for Mac (Windows coming soon). SoftRAID makes it a breeze to create RAID volumes by helping you through the entire process. With multiple RAID options, you decide what you’re using your RAID volume for and how much space to allocate to it. It's that simple to create your preference of speed and/or redundancy for your data volume.

SoftRAID highlights
- Flexible: create RAID 0 and 1 volumes with SoftRAID Lite XT
- Verify: volume validation ensures sectors can be read, parity is correct, and any potential volume failure is minimized
- Certified: drives are validated before use to ensure they are safe for data storage
- Vigilant: predictive warnings help protect against unexpected drive failure
- Outperforms: up to 86% faster than AppleRAID
- Thorough: full TRIM support improves internal and external SSD performance in all RAID levels

Swap and Identify Drives Easily
ThunderBay 8 makes it easy to keep large data sets organized for every project thanks to its eight hot swappable drive bays. Whether you’re using 2.5-inch or 3.5-inch HDDs and/or SSDs, the drives mount in alphabetically labeled trays for easy identification and are secured by a thumb screw. If you want the freedom to access an extensive collection of drives quickly, you can create a drive “bullpen” with additional OWC drive trays (sold separately).

As Secure as a Bank Vault
With a locking front panel and security slot on the backside, the ThunderBay 8 is like an ironclad vault l for your data. Plus, with front panel LEDs indicating the status of each drive, you’ll know at a glance if your data is secure.

See More, Do More
ThunderBay 8 isn’t just about high-capacity, high-performance storage. It’s about giving you all the options you need to work at your best. Attach a 5K Thunderbolt display or two 4K displays. Place a USB 3.1 device at the end of a daisy chain. With an extra Thunderbolt 3 port, you have the flexibility to add more devices to your workflow and master any task at hand.

Secure Your Workflow with OWC ClingOn
Greatly reduce — if not eliminate — cable strain and accidental disconnects with the OWC ClingOn. These custom cable stabilizers (sold separately) screw into the ThunderBay 8's housing to secure your Thunderbolt 3 and USB-C connections and prevent work session interruption and possible data loss.
