You can't boot a drive > 2.2TB on any Windows 7 PC as a primary MBR drive though unless you have the latest mobo with UEFI (EFI) interface. Chances are most people are using an SSD + large storage drive anyway.

That is exactly what I wrote about! There is one important and wrong statement in the article:

"...the standard BIOS cannot work with GPT partitions. That is, the OS will see such partitions, but must be installed on an MBR one for the computer to boot it up. It is only computers with the mentioned EFI (instead of BIOS) that can boot up from GPT partitions but EFI mainboards are very few as yet..."

This is bullshit. BIOS can work with GPT. In fact, BIOS can work with any partition scheme, if the first 440B of the drive contain beginning of the bootloader. It is only Microsoft fault, that Windows in 21st century boots like MS-DOS and use obolete MS-DOS partitioning scheme (containing only 4 partitions up to 2TB in the table). Blame Windows, not BIOS. Other OSes can boot GPT on BIOS machine.
