Depends a lot on partition setup and type of drive actually.
Newer drives have more sectors per angle on the outer side, since it is
pysically larger, and thus reading the data is faster (head speed is
faster relative to the pisical media on a constant speed motor).
Others say that if you place the swap in the middle between to active
partitions it will be statiscly faster getting there since the head will
be traveling back and forth.
I don't seem to have managed to be very coherent, I hope its
understandable enough if anyone is actually interested ;)
