Having a page file on the OS/boot partition lets you make minidumps - which is useful if your computer crashes. Otherwise it shouldn't really matter all that much.
In theory, you would want files that would need to be accessed quickly on the
inner part of the hard drive that has a higher linear velocity- practically though, the difference is not likely to be that great. Page files are also meant to be a temporary space, and a way to handle needing more ram - you'd probably consider this largefile/bulk storage, and can get fragmented within a partition. Trying to put a pagefile in a predictable fashion on a specific physical part of a hard drive will need you to do a seperate partition just for that, almost the way linux has a swap partition.
You're unlikely to have any benefit from moving the swap file from the OS to storage partition
