If the Paging File is enabled, then Windows 7 takes full advantage of it every time it is more efficient to do so, even if you never
use more than like 20% of your installed memory (even if you have way more memory installed than you'll ever need).

I have tried it both ways, moitoring writes and reads, and YES, it IS used even with 8 Gigs of RAM. I left mine at 2 Gigs, but it is just fine at 1 Gig. Writes to the page file are sequential now. Page file is also read at boot time to speed things. Keep it on your SSD where it belongs.

another question: doesn't superfetch run in the ram?
one more question: what do you find you need the paging file for with 8 gb ram? i have found ive never needed it for anything just curious why you think this or what you have found that needs it

Superfetch does run in Ram, but it also does a lot of reading and writing. Remember, the object of superfetch is to copy program stubs from SLOW hard disk to fast RAM. With an SSD, this is not needed, since the SSD reads so fast. I recommend you try it with it on, then try it with the service disabled. You likely will not see any slow down, actually a speed up since more RAM is available for other things and there will be a marked decrease in disk writes/accesses.
Windows 7 does use the page file IF PRESENT to keep things effecient. Several programs use it like VMWARE, some games, graphics software, MS office, etc... It will only use it when it is effecient to do so. With 8 Gigs of RAM a 1 GIG page file is plenty. Remember: the page file in Windows 7 is more sequential now, and therefore much more efficient. One of my MS sources also told me that there is some cached boot code in it to speed up boot, but to be honest, I haven't seen a difference. I can tell you that it IS smoother with even a 512 Meg page file on the SSD.
Try it both ways with your read-world load and decide for yourself. There is no bench-mark for it other than your gut. That is why it is so debated.
EDIT: 10/12/2010: I am no longer recommending that you move your temp files or internet files off the SSD. It does not increase performance, but decreases it a bit.
The original reason I recommended it was to save space if it gets tight.
So I say that this proves once and for all that if you have Windows 7 on a solid state drive, then it's better to leave the Paging File enabled, on the SSD, and at its default setting - even if you have the ability to move it to a hard drive.
