ThunderBay 4 mini Four-Bay Thunderbolt 3 External Drive Enclosure
Big RAID System Performance in a Compact Design
The ThunderBay 4 mini is a compact data storage enclosure that you can populate with new or existing 2.5-inch HDDs or SSDs. It’s big on performance and flexibility, yet ThunderBay 4 mini is about the length of a pencil and can weigh as little as 3.1 pounds with drives.
The rugged heat-dissipating aluminum enclosure features two Thunderbolt 3 (Thunderbolt 2/Thunderbolt backward compatible) ports for up to 1556MB/s speeds, so you have more than enough bandwidth to handle personal and business backups — all the way up to today's highest resolution audio, photo, and video formats. If you are seeking big RAID performance that's small enough to fit on a desk, in a rack, or on a DIT cart, your wish is now a reality.
Speed, size, and convenience — the OWC ThunderBay 4 mini provides everything a demanding workflow requires.
A New World of Drive Use Flexibility
With four drive bays, you can mix or match different brand and capacity 2.5-inch SSDs and HDDs. Use mixed drives independently or combine drives as a RAID with the included SoftRAID setup and management software. You can populate this empty enclosure with your own drives, or choose a pre-configured capacity solution to achieve your desired balance of storage, performance, and data redundancy.
Expand production capabilities in industry-leading creative platforms like Final Cut X, Avid Pro Tools, Apple Pro Logic, and Adobe Lightroom, edit large images, manage massive photo and audio libraries, store drone videos, use it as a transport drive…whatever the day or project demands, the ThunderBay 4 mini is the perfect workflow solution.
Install or Swap in Minutes
Want to access a drive or expand your storage capacity? Simply open the front panel security lock to access the four individual bays. Drives mount to a tray that slides back in and automatically plugs into a drive connector so you can get back to work in minutes.
Store More, Go Faster
With the ability to daisy-chain you can add up to five additional ThunderBay 4 mini solutions to create massive storage capacities. Merge them with SoftRAID for even more flexibility, capacity, and capability. Or if speed is what you’re after, connect multiple ThunderBay 4 mini solutions to multiple Thunderbolt 3 ports on your Mac or PC to achieve exponential speed capabilities.
Professional Grade = Ready to Work
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every ThunderBay 4 mini enclosure undergoes a multi-step performance certification prior to shipping. This ensures your ThunderBay 4 mini enclosure arrives ready for demanding use.
