paging files are so much slower then ram that i doubt u would see any performance difference no matter were thy are located.
but what would probably help the most.. is if u did this... move the 'slave' HD over to the other EIDE cable, so its in the 'Secondary Master' position... then disable pagingfiles on the 'Primary Master' HD. and just use the secondary for paging. then u can also delete the 2nd partition on the primary and have more space.

for the avage user, the default 4kb cluster size is fine(I imajine, unless someone points out a reason y) ,theoreticaly the best performance would be to have a cluster size, thats the same size as the avage file size on the disk. but im not shur if it actually makes a difference anymore, HDs are so big nowadays that thy can always be defragmented... raising the cluster size is used just to limit posible fragmentation.. but raising the cluster size scrificess disk space... .example- [not actual math,just numbers]-> a 200gb disk, with 4kb cluster, equals 185gb's after formatting... a 200gb disk, with 64kb clusters, equals 175gb's after formatting.
----------------------------------------------------
see wat i mean... so if someone points out otherwise, i think its more eficent to just stick with the default cluster size.
