Improved reliability - LRU: 10,000 hours Optical drive: 40,000 hours versus 2,000 hours for tape units.

•  
Reduced maintenance cost-No scheduled maintenance required. On-condition maintenance is indicated by a built-in test and can be performed on aircraft.

•  
Improved media durability.

•  
Simplified ground processing-Direct, random access PC readability eliminates need for the classic and time-consuming data-transcription process.
