NOTE 1. Not every OS can support disk space up to 2 TB.
NOTE 2. When RAID volume is created, it can be initialized on the background. RAID volume
can be immediately available without completing the fully initialization.
NOTE 3. Drive coercion refers to the ability of the RAID controller to recognize the size
of the physical drives that are connected and then force the larger drives to use only
the amount of space available on the smallest drive. Drive coercion as implemented in these
RAID controllers also allows an option to map out a reserved space to compensate for slightly
smaller drive sizes that may be added later. It is 64 MB by default and cannot be changed.
