Hardware RAID solution has its own processor and memory to run the RAID applicaiton. In this implementation, the RAID system is an independent small computer system dedicated to the RAID application, offloading this task from the host system.

  • Enhanced protection in case of power loss. Hardware RAID implementation typically keep track of in-progress writes in non-volatile hardware.

  • Not vulnerable to virus. RAID arrays are completely independent of the host system and OS. No data integrity issues occur if the host system fails.

  • Offloads the RAID task from the host. Best suited for complex RAID 5 or RAID 6 scenarios which usually offers best cost/performance ratio.

  • Dedicated GUI and software to build and maintain the RAID, easy setup and maintenance of the RAID array.

  • Supports advanced RAID features, include disk hot plug, array-level migration and online capacity expansion.
