* This class was created in an effort to reduce the complexity of the
* GParted_Core class.
* This class provides support for motherboard based RAID devices, also know
* as Fake RAID.
* Static elements are used in order to reduce the disk accesses required to
* load the data structures upon each initialization of the class.
