Question $22$

In a healthcare organization's health information system, RAID $5$ is implemented to enhance data storage efficiency and reliability. Considering RAID $5\text{'}$s mechanism of striping data with parity across multiple disks, which of the following outcomes would most likely be observed if one of the disks in the RAID $5$ array fails?

There is no impact on system performance or data reliability, as RAID $5$ does not support disk failure recovery.

No data is lost due to the parity information allowing data reconstruction, using XOR verification.

The failed disk causes an irreversible loss of some data, but the system remains operational.

The entire system crashes and all data is immediately lost.
