Anecdotal evidence, but I often find WD drives to be faster than their Seagate cousins, even at lower rotation speeds. I wonder if this is because of better firmware optimizations or because of higher platter density. Maybe it's both. Or maybe WD lies about their rpms ;) Hitachi/HGST, now owned by WD, also makes really fast drives. Their 7200rpm 2.5" drives are the fastest laptop drives I've ever used, except SSDs.
