Conventional wisdom turned on its head.

Hardware RAID has long been thought to be superior to software RAID, but we've now combined the massive performance and capacity of ThunderBay 4 with a robust, proven software RAID engine to provide breathtaking performance, flexibility, and reliability.

Software RAID + ThunderBay = WHOA!

Over a year ago, OWC partnered with SoftRAID to bring enhanced storage capabilities to the Mac, and we're now seeing that dream become a reality. SoftRAID XT combines advanced RAID modes, fast performance, monitoring, e-mail notification, and fast rebuild capabilities that only software RAID can deliver.

Monitoring + Notifications

SoftRAID XT lets you easily setup drive monitoring and e-mail notifications to keep you informed about your ThunderBay's performance and drive health. Helping you to maintain mission critical workflows.

Better than Hardware RAID Performance

ThunderBay 4 and the SoftRAID engine 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 XT 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.
