Actually, as I think about it, >2TB with BIOS is a dead end for most of the market because Windows on BIOS requires MBR, and thus far there's no extension for MBR beyond 32-bit addressing. There's sort of a crude work around that can allow up to 4.4TB disks with MBR, requiring two partitions; since MBR specifies partitions with starting LBA and number of partitions rather than ending LBA. I don't know this yet, but I suspect this is how Apple has implemented 3TB support for CSM booting (totally ill advised in my opinion). GRUB+Linux of course can use GPT in such a case, so long as the BIOS bugs are fixed to tolerate GPT (which some BIOS's notably Lenovo) the larger disk sizes are bootable.
