Notes:
a. If only one hard disk has been assigned to the array, RAID level 0 will be
automatically assigned and the pop-up menu does not appear.
b. If only two hard disks are assigned to the array, RAID-5 is not selectable,
since at least three hard disk drives in an array are necessary to assign
RAID level 5 to one of the logical drives.
c. Define any RAID 5 logical drives first. This is because the first logical
drive seen will be the first RAID 5 drive created and will be assigned
drive letter c:. In this way, the operating system will be installed on a
RAID 5 drive.
d. The three RAID levels (0, 1 and 5) can be mixed in the same array
allowing the user to chose the optimum RAID level for each data type.
e. It is, however, not recommended to mix RAID 0 with the others levels if a
hot-spare drive is defined, since an automatic rebuild would not be
possible.
3. Assign the RAID level wanted and press Enter.
The logical drive size pop-up menu shows the space available in this array
for logical drives.
RAID 5 has been chosen in this example.
