A desktop system configured with a hardware RAID 1 array utilizing two 1 TB SATA SSDs exhibits severe latency during write operations. Storage diagnostic software shows that one drive is reporting a high count of reallocated sectors via S.M.A.R.T. monitoring, though the RAID status remains operational. Which of the following actions should the technician take to resolve the issue while protecting data integrity? (Select TWO).
- Perform a verified backup of all critical data residing on the array to an offline or secondary storage device.Answer
- Replace the drive exhibiting S.M.A.R.T. errors with a new SSD of equal or greater capacity and initiate an array rebuild.Answer
- CFormat the drive reporting reallocated sector errors and convert the RAID 1 array to RAID 0 to increase performance.
- DDelete the RAID volume configuration in the controller utility and initialize both SSDs as standalone drive letters.
Answer
The technician must back up critical array data to an external location and replace the failing SSD with a drive of equal or larger capacity to rebuild the mirrored volume.
When a drive in a RAID 1 array begins exhibiting S.M.A.R.T. predictive failure indicators such as excessive reallocated sectors, the safest approach is to create a complete secondary backup of all data first. Following data backup, replacing the failing drive with a healthy drive of equal or greater capacity allows the controller to rebuild the mirrored volume without risking data loss.
