A traditional BIOS or UEFI running in CSM requires an MBR formatted disk since the bootloader must be started from the first 512 bytes on disk. I have to boot ESXi on my ProLiant ML10 off a flash drive because my 3TB disk would become a 2TB disk otherwise.

Did you hear about "hybrid MBR"?

Hybrid MBR is an extremely fragile and hackish technique to make crappy old firmware boot larger disks. In general I want my whole 3TB drive allocated to VM storage instead of partitioning it up so ESXi has somewhere to live, so just running that off an easily replaceable USB key is a lot simpler to maintain.
