SOFTRAID: CONVENTIONAL WISDOM TURNED ON ITS HEAD
It’s often thought that hardware RAID is better than software RAID, but we’ve proven that not to be true. We've combined the performance and capacity of the ThunderBay 4 with our robust SoftRAID engine. Experience breathtaking performance, multi-enclosure capability, advanced drive monitoring, e-notifications and downloadable updates. Once you do, you'll see how hardware RAID doesn't even come close.

THE BETTER AND SIMPLER WAY TO RAID
We created SoftRAID to make it easier to maintain mission-critical workflows to save you time and money. With SoftRAID you no longer need to be locked into expensive hardware RAID technology that’s not upgradeable or expandable. SoftRAID future-proofs your data and storage with software updates that provide cutting edge capabilities and robust stability.

SoftRAID takes advantage of your computer's processor versus the slow processors found in most hardware RAID enclosures. The result is a fast and flexible RAID array with no discernible impact to your favorite apps. SoftRAID drive certification tells you whether or not a drive is up to the task before creating a RAID array. Advanced monitoring tools work behind the scenes to keep your RAID running in tip-top shape.

SoftRAID protects your data by alerting you to issues before anything happens, ensuring you're protected when you’re on a critical deadline. SoftRAID rebuilds your RAID in a fraction of the time it would take a hardware RAID to complete the same task, sparing you from significant downtime when you're ready to upgrade or replace a drive.

WORKFLOW AND STORAGE SOLUTIONS FOR PROS
