ThunderBay 4 mini
8.0TB Professional Grade 4-Drive SSD Thunderbolt 2 Solution For Mac and Windows PC
Featuring SoftRAID XT
The Perfect Combination of Speed, Size, and Convenience for Permanent Access to Your Data
Big RAID System Performance in a Compact Design
The ThunderBay 4 mini SSD equipped solution is big on performance and flexibility yet sized about the length of a pencil. The rugged heat-dissipating aluminum enclosure features two Thunderbolt 2 (Thunderbolt 10Gb/s backward compatible) ports for up to 1346MB/s real-world 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.
A New World of Drive Flexibility
With four hard drive populated bays, you can use the drives independently or combine drives as a RAID with the included SoftRAID setup and management software. The ThunderBay 4 mini is also perfect for repurposing or maximizing bare 2.5-inch HDDs and SSDs you already own.
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 another 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
