I've been wondering from time to time if partitions position
can be a (probably modest, of course) performance gain factor.

If I create a partition at the beginning or end of the disk,
is this going to have a determined platter physical position?

I remember having heard that every manufacturer has its own
allocation logic.

Has anyone got some information, just for curiosity?
