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 extra physical drives (P
n
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.
