What you're referring is taken care of by the I/O Scheduler. But ofcourse the requests take longer but its not because the HDD's head is moving back and forth (the head moves in the same direction like an elevator, the I/O scheduler makes sure about that (Just imagine how slow the system would otherwise be!), but because the head is like an elevator and you have to wait. - Criticism welcomed about that.
