Costs and limitations of RAID 5 protection

 

There are costs and limitations when using RAID 5 protection.

• The system is only capable of handling one disk-unit failure. If more than one disk unit fails, the system may also fail depending on the disk pool configuration.

• Device parity protection can require additional disk units to prevent slower performance.

• Restore operations can take longer when you use device parity protection.
