same capacity as the smallest drive in the array. The excess capacity of any larger drives
is wasted because it is unavailable for data storage.
The probability that an array will experience a drive failure increases with the number of
physical drives in the array. If you configure a logical drive with RAID 5, keep the probability
of failure low by using no more than 14 physical drives in the array.
For conceptual information about arrays, logical drives, and fault-tolerance methods, and for
information about default array configuration settings, see the HPE Array Configuration Utility
