Which RAID Configuration Offers No Fault Tolerance?

Which of the following RAID configurations offers no fault tolerance?

a. RAID 3

b. RAID 0

c. RAID 5

d. RAID 1

Final answer:

RAID 0 is the configuration that offers no fault tolerance. It does not include redundancy or data backup, therefore when one drive fails, all data is lost.

RAID, or Redundant Array of Independent Disks, is a method used to store the same data in different places on multiple hard disks. By placing data on multiple disks, input/output (I/O) operations can overlap in a balanced way, which improves performance.

The RAID configuration that offers no fault tolerance is RAID 0. RAID 0 does not include any redundancy or fault tolerance measures. As a result, if one drive fails in a RAID 0 configuration, all data stored on that array is lost as there are no backup copies.

Unlike RAID 1, 3, and 5 which provide some form of fault tolerance by distributing data across multiple drives with redundancy, RAID 0 sacrifices data protection for improved performance.

It is essential to understand the implications of choosing a RAID configuration that offers no fault tolerance and to implement appropriate backup and recovery strategies to prevent data loss in case of drive failure.
