This may sound like a stupid question to some, but I haven't really been able to find a definite answer...
I just bought an 80GB sata drive.
I'm replacing my old 120GB IDE drive with the 80GB sata for my OS installation, and just going to use the 120GB drive for backup and such.
I was wondering if I should move my page file to the 120GB drive, even though it operates slower?
Would I notice a difference in performance?
It's not a stupid question - there's no such thing. The stupid folks are those who don't ask questions.
You may notice a better performance but it depends where on that drive the swapfile is positioned. Put it on there now and it will mix in and fragment amongst all the other fragments which are already there. If you defragment the drive first then wipe the free space using, say, CCleaner from http://www.piriform.com, you will have a better chance of improving speeds but there's really no substitute for increasing RAM.
