The boot order in the BIOS has no effect on the device discovery and

I've seen just one instance reported where an externally connected
USB drive got /dev/sda whereas the internal mSATA got /dev/sdb.

Yes, I just got a report of a case where the internal SATA drives was sdb and sdc, and sda was probably the internal all-in-one card reader. But I never observed such a case myself.

This was from someone who was about to dd copy the drive (which is
why they checked).

Hehe, we all know that sd* names are not reliable.
