I was more concerned about, say, an OS -installer- becoming confused
and stepping on a disk, perhaps by trying to write an MBR. I've seen
similar issues before.
I seriously doubt there can be any speed difference at all.
Whether or not a partition is there is just a matter of where
the offset for the data area starts.
And I'm a big believer in reducing my own cognitive load and
chances for screwups when it comes to manipulating disks.
There's always a first time for a big oops. :)
