Actually, 4k native drives can use MBR up to 16 TB. The limitation on
the MBR partition table is 32 bits to address sectors, so larger
sectors => higher addressable size. Some of the fakeraid controllers
on the market take advantage of this fact and report a 1k or 2k
physical sector size to allow MBR partitioning on larger arrays.
