A technician is troubleshooting a workstation that contains two hard drives in a RAID 0 configuration. One of the drives has failed. Which of the following BEST describes the status of the data on the array?
The data is unrecoverable because RAID 0 does not provide fault tolerance.
The data on the remaining functional drive is still accessible, but files are incomplete.
The performance of the array is degraded, but all data remains accessible.
The data can be fully restored by replacing the failed drive and rebuilding the array.
RAID 0, also known as striping, improves performance by splitting data across two or more drives. It provides no redundancy or fault tolerance. If a single drive in a RAID 0 array fails, the entire array becomes inaccessible, and all data is lost. Redundant configurations like RAID 1, RAID 5, or RAID 10 are required for data to be recoverable after a single drive failure.
