Which RAID type provides high performance but doesn’t provide any redundancy of data?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 1+0
The answer: A) RAID 0
The Redundant Array of Inexpensive Disks (RAID) level 0 is synonymous with striping, a term that describes the storage of data across multiple disks where the files are split between drives. This provides performance enhancements, but it doesn’t provide any redundancy.
The incorrect answers:
B) RAID 1
RAID 1, or mirroring, duplicates data but doesn’t provide any significant performance increase.
C) RAID 5
RAID 5 (striping with parity) duplicates files across disks and also adds an additional parity block for redundancy.
D) RAID 1+0
RAID 1+0 (also called RAID 10) describes a combination of RAID 1 and RAID 0 where the data is both mirrored and striped.
