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.
