ThunderBay 4 mini
4.0TB Professional Grade 4-Drive SSD Thunderbolt 2 Solution For Mac and Windows PC
Featuring SoftRAID Lite 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 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 order as an empty enclosure and populate with your own drives, or choose a variety of pre-configured capacity solutions to achieve your desired balance of storage, performance, and data redundancy.
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
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.
