Well, DUH! Must have had my head in my old 486 DX2-66. Brian's absolutely correct that current IDE specs no longer push the drives to operate at the "lowest common denominator" as they did several years ago.
The only "obstacle" in placing a swap (pagefile in Windows XP) in a different location would be in putting it on a second hard drive with a much slower seek time. Placing the swap (pagefile) on the same hard drive but different partition has other benefits over the same partition as the operating system, but doesn't increase the efficiency because it still is on the same physical drive.
Best benefit of moving the swap (pagefile) to a different physical hard drive is if that drive is the least used between the system drive and "storage" drive, since a seek across several tens of fragmented tracks is what needs to be avoided.
If, after switching the swap (pagefile) to the second physical hard drive doesn't give any benefits in access time, then another - solvable - problem probably exists: You need more RAM, because your system usage is not able to use all the available memory (faster) and has to rely on trading files to the physical hard drive (slower).
