After that the new disk space will be displayed as Unallocated at the end of the raid array, then you can extend the RAID 5 partition with the new disk space …

How many drives do you need for RAID 5?

three drives
RAID 5 provides fault tolerance and increased read performance. At least three drives are required. RAID 5 can sustain the loss of a single drive. In the event of a drive failure, data from the failed drive is reconstructed from parity striped across the remaining drives.
