I believe so...........
Executive Diskeeper is a great program. I beleive it defrags the page file as well, unlike the built in defrag program
According to Diskeeper, the built in defrag program to windows is diskeeper, just scaled down and does not defrag the pagefile.
The program shouldnt just stock pile all your data on one drive. If I'm correct, striping makes it look like ONE big drive so it should just defrag it evenly.
