Question 1

Describe RAID level 5. What are the advantages of using RAID level 5 over other types of RAID?

Accepted Answer

RAID level 5 replaces RAID levels 3 and 4, and is the most common RAID configuration as of this writing. It is commonly referred to as disk striping with parity. As with RAID levels 3 and 4, it requires a minimum of three hard disk drives for implementation; however, the parity information is not stored on a separate drive, but is intermixed with data on the drives that make up the set. This offers better performance and fault tolerance; if any drive in the RAID configuration fails, the information on the other drives can be used to regenerate the lost information after the failed hard disk has been replaced. If two hard disks fail, the system must be restored from a backup device.
