A number of users are indicating that access to a network file server is responding very slowly when reading or writing to the share. The server administrator notes that a drive has failed in a four-disk RAID 5 array. The array is running in a degraded state because no hot spare was configured. After replacing the failed disk, which of the following steps would be BEST to take to prevent slow response after a drive failure?
A. Add a drive to the array, but do not configure it as a hot spare.
B. Add an additional hard drive, and convert the volume to a RAID 6 configuration.
C. Add an additional hard drive, and convert the volume to a RAID 10 configuration.
D. Add a drive to the array, and configure it as a cold spare.
