I know the rationalization behind that idea, of course, but I have to
strongly disagree with it.

Disk head seek time is the real bad guy. Keeping the more often accessed
areas at the center of the disk will give you performance improvements,
specially with new disks.

Yes, putting the swap on the least used drive/area will potentialy
increase the longevity of the disk media, but can cause the mechanical
part of the disk (hello Maxtor!) to break earlier. In any case, disks on
servers should be replaced each 2 years.
