# from sammkfs manpage:
#     Data alignment refers to matching the allocation unit of the
#     RAID controller with the allocation_unit of the file system.
#     A mismatched alignment causes a read-modify-write operation
#     for I/O that is less than the block size.  The optimal
#     alignment formula is as follows:
#
#     allocation_unit = RAID_stripe_width * number_of_data_disks
#
#     For example, if a RAID-5 unit has a total of 8 disks with 1
#     of the 8 being the parity disk, the number of data disks is
#     7.  If the RAID stripe width is 64 kilobytes, then the
#     optimal allocation_unit is 64 * 7 = 448.
