Drives of the same brand/model/capacity might
not have the same block number.
The basic read/write unit of a hard drive is Block.
If the drive members in one logical drive have
different block numbers (capacity), the minimum
block number among all the member drives will
be chosen as the maximum block number for the
RAID configuration.
You may assign a Local/Global Spare Drive to a
logical drive whose member drive's block number
is smaller or equal to the Local/Global Spare
Drive's block number but you may not do it vice
versa.
