Drive arrays and fault-tolerance methods Drive arrays The capacity and performance of a single physical (hard) drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when drives fail. Connecting - HP ProLiant DL380p | Configuring Arrays on HP Smart Array Controllers Reference - Page 107
