Does any RAID configuration provide a complete solution to fault tolerance in servers?

RAID (Redundant Array of Independent Drives) configurations typically range from RAID 0 to RAID 10.

While no level can offer a complete solution to fault tolerance, RAID 10 comes closest to it.

RAID 10 is also known as hybrid RAID and it combines mirroring and striping techniques.


  • Has high I/O rates
  • RAID 10 array can sustain multiple simultaneous drive failures
  • Provides a performance boost


  • Very expensive and has a high overhead
  • Lowered sustained performance – as all drives must move in parallel to proper track
  • Very limited scalability at a very high inherent cost
