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 extra physical drives (Pn in the figure) to a system increases the total
storage capacity but has no effect on the efficiency of read/write (R/W)
operations. Data can still be transferred to only one physical drive at a time.
