Only BeyondRAID allows you to instantly expand your capacity by simply adding a drive or replacing the smallest drive with a larger one, even when all five drive bays are full.

  • Protection from Two Drive Failures
    Enable the dual-drive redundancy option to protect your data from failure of up to two hard drives. It’s all done with a single click, and without ever losing access to your data.

This preemptive “scrubbing” helps ensure your data is being written only to the healthy areas of your drives, and that your data is always safe. Even if a drive fails, Drobo S keeps your data in the safest state possible, utilizing the available space on the remaining healthy drives.

  • Windows, Mac, Linux
