    NASware optimizes power use resulting in significant power savings and lower hard drive operating temperatures. This improves the overall reliability and performance of the drive and reduces the NAS cost of ownership.
  • Intelligent error recovery
    With built in intelligent error recovery controls, NASware also prevents hard drives from being dropped off the RAID due to extended error recovery. This provides more availability and less down time rebuilding the RAID.
