RAID Specifications

Question 1

What does RAID do?

Answer 1

RAID (Redundant Array of Independent Disks) stores data on multiple hard disks to improve data reliability and improve performance.

Question 2

RAID 0

Answer 2

This configuration splits data equally between two + hard drives to improve performance. Does not provide protection/redundancy. striping without parity

Question 3

RAID 1

Answer 3

This configuration duplicates data between two+ hard drives to provide data protection/redundancy. Does not improve performance.
mirroring without parity.

Question 4

RAID 5

Answer 4

Configuration uses three hard drives and uses parity data to provide data protection and redundancy. striping with distributed parity

Question 5

RAID 6

Answer 5

This configuration uses two sets of parity data to provide better protection and redundancy, using at least four hard drives. striping with double distributed parity

Question 6

RAID 1 0

Answer 6

This configuration uses four hard drives and duplicates data across two set of mirrored hard drives, and striped for improved performance. combination of RAID 1 and RAID 0
