Appendix F Selecting the Best RAID Level 93
FIGURE F-1 Nonredundant Arrays (RAID 0)
RAID 1 Arrays
A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the
other (the same data is stored on each disk drive). Compared to independent disk
drives, RAID 1
arrays provide improved performance, with twice the read rate and
an equal write rate of single disks. However, capacity is only 50 percent of
independent disk drives.
If the RAID 1 array is built from different-sized disk drives, drive segment size is the
size of the smaller disk drive, as shown in this figure.
