Big RAID System Performance in a Compact Design

The ThunderBay 4 mini is perfect for repurposing or maximizing 2.5-inch SSDs for a compact data storage solution. It’s big on performance and flexibility, yet ThunderBay 4 mini is about the length of a pencil and weighs only 3.1 pounds with SSDs. The rugged heat-dissipating aluminum enclosure features two Thunderbolt (Thunderbolt 2/Thunderbolt backward compatible)1 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.

Store More, See More, Do More

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 (USB-C) ports on your Mac or PC to achieve exponential speed capabilities. Beyond storage, the sky is the limit for what you can connect. Attach a 5K Thunderbolt display or two 4K displays. Place a USB 3.1 device at the end of the chain. With an extra Thunderbolt (USB-C) port, you have the flexibility to add to your daisy-chain and master any task at hand.
