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 2 (Thunderbolt backward compatible) ports for up to 1346MB/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.
