Unless they're 10kRPM or faster. Not sure if it's still the case, but these drives used to have smaller platters to reduce the seek time, so they were pretty much 2.5" drives in a 3.5" shell. I believe the WD Raptor was (is?) almost a 2.5" drive with a heatsink large enough to bring it up to 3.5" [1] - this is going back a few years now though, I don't know if it is still true. So given equal RPM the 2.5" drive should have a faster full-stroke seek, but as has been pointed out, an SSD would be even better in this respect. Cheers, Adam.
