ThunderBay 4 with SoftRAID offers faster performance than many competing 4 or even 5-bay hardware RAID external drives – benefiting from modern processors that are both fast and designed for exceptionally high-performance RAID management with no real-world impact on apps or tasks.
Flexible + Robust
SoftRAID is extremely flexible and can easily be updated, reconfigured and used across multiple enclosures to provide an amazing amount of robust options to empower you to make the most of your ThunderBay workflow.
