Is this something you want to solve, or just a point of interest?
With some motherboards, the BIOS boot order seems to rearrange what it
thinks of the hardware, and there's various parts in my UEFI where
I can rearrange how it considers the drives. Leading to some
shenanigans to get it to do what I want - act in a logical manner. It
has a separate drive order list, and a separate boot priority list.
Logically speaking, if you skip a port (you're using 1, 3, 4, 5, 6),
/dev/sdb could be overlooked, or applied to the drive in the 3rd port,
if a board enumerated the ports in sequence.
Some just look for bootable code where you tell it to look.
The old GRUB made your boot drive hd0, but I think that only mattered
to itself. The new GRUB is nightmare to deal with.
It can also be related to fastest hardware to get recognised. If some
drive is quicker at waking up from cold boot, it may be the first
drive.
