"When it comes to making sure years of content is easily accessible in a speedy manner, the ThunderBay provides that and much more."
“I use Thunderbay for storing all the data I took over the years. I take huge risk in taking the best possible images. I do not want to loose them at any price."
Still The Standard. Now Even Better.
Client work adds up fast, and so does the backup copy, the archive, and the footage nobody's ready to delete yet. OWC ThunderBay 4 organizes it all in one four-bay enclosure with up to 128TB of RAID-protected capacity. Every solution ships configured for RAID 5, so a single drive can be replaced without putting your files at risk. Two Thunderbolt 5 ports carry a full 80Gb/s connection to your computer and pass that same bandwidth downstream, giving added displays, drives, and devices far more headroom than what past ThunderBay 4 models offered. Included free trial of Strada lets your remote team reach your files the day this storage powerhouse arrives. The design looks nearly identical to the ThunderBay 4 that's been refined since 2014. That's not a lack of imagination. That's what happens when you get it right the first time, and keep getting it right.
Capacity to Match Serious Workflows
Four drive bays hold up to 128TB in a single enclosure, giving photographers, video editors, and DITs room for active projects, archives, and backups together. As larger drives become available, upgrading is as simple as swapping drive trays.

Two Thunderbolt 5 Ports Keep You Connected
One Thunderbolt 5 host port connects to your Mac or PC at up to 80Gb/s, double the bandwidth of the previous ThunderBay 4 model. The second downstream Thunderbolt 5 port carries that same bandwidth forward, so displays, additional storage, and other Thunderbolt or USB4 devices can perform at their best. Daisy chain up to five devices without any of them taking a back seat.
Built Right from the Start
Every ThunderBay 4 is built from a solid all-aluminum enclosure with a locking front panel, flow-thru vented cooling, and a quiet 92mm fan, a design refined through more than a decade of real-world studio use. Vibration-absorbing feet keep long sessions steady, and every solution ships after OWC’s multi-step performance certification.
Your Drives, Your Configuration
Upgrade drives as your capacity needs grow and maximize your enclosure investment with hot-swap thumbscrew drive trays.
Works with Mac and PC
ThunderBay 4 connects to Thunderbolt 5, Thunderbolt 4, and USB4 equipped Macs and PCs, plus Thunderbolt 3 equipped Macs. For RAID setup, choose SoftRAID on either platform, or use macOS Disk Utility RAID Assistant, Windows Disk Management, or Windows Storage Spaces.

RAID 5, Required and Ready
For many professional workflows, RAID is a requirement, not a convenience. Major content platforms such as Netflix call for RAID 5 or above when backing up OCF (Original Camera Files). ThunderBay 4 solutions ship configured for RAID 5, distributing data and parity across all four drives to keep your files accessible through a single drive failure. SoftRAID handles setup and keeps watch on drive health in the background. RAID 0, 1, 4, 6, 6+, 10, and JBOD are also available for workflows with different priorities.

SoftRAID makes the RAID
Any drive can hold data. Not every drive can protect it. OWC’s SoftRAID RAID management software builds RAID 0/1/4/5/6/6+/10 arrays for speed, redundancy, or both - and keeps them healthy by monitoring performance and catching failures early so you never lose a project to a dying drive.
- NEW RAID 6 and RAID 6+: Dual-Drive failure protection can protect your most critical data.
- Blazing-Fast Performance: Engineered with the latest driver technology to deliver maximum RAID speeds on macOS and Windows.
- Versatile RAID Options: RAID 0/1/4/5/6/6+/10, every level optimized to maximize the bandwidth of your drives and interface. (RAID 6/6+ requires macOS 27).
- Proactive Disk Protection: SoftRAID Monitor detects and warns you of potential drive failures before they happen on HDDs, SSDs, and NVMe.
- Cross-Platform Compatibility: Easily move Apple-formatted APFS and HFS+ volumes between Mac and Windows via built-in OWC MacDrive technology.

The Cool Quiet Type
External drives for content production need to offer more than just speed and capacity for massive files. They also need to offer quiet and secure reliability. You’ll work confidently and free of distraction with ThunderBay 4’s unique design. Its heat-dissipating aluminum housing utilizes “flow-thru” venting, a low-turbulence fan, and a drive-isolating design coupled with vibration-absorbing feet that reduces sonic resonance. And you’ll always keep your data safe and secure with the locking faceplate and backside security slot.
Pre-Tested = Ready to Work
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every ThunderBay 4 undergoes OWC's multi-hour "burn-in" performance certification prior to shipping. This ensures your ThunderBay 4 arrives operating properly and immediately ready for demanding use.
