These partitions are not seen by the operating system. Rather,
they are the building blocks of a virtual disk. This virtual disk is
seen by the operating system as a single disk drive.
Depending on the type of RAID array created, the virtual disk
may be larger than any of its component partitions. For example,
a stripe set (RAID 0) created from two partitions presents a
virtual disk drive almost twice the size of the individual
partitions.
Each of these partitions can be used by only one array at a time.

A subdivision of a virtual disk. Some RAID controllers allow
you to divide the virtual disk into multiple parts, or partitions.
Each partition is seen by the operating system as a separate disk
drive.
